Enhancement the economical and environmental aspects of plus-zero energy buildings integrated with INVELOX turbines
تقویت جنبه های اقتصادی و زیست محیطی ساخت انرژی بالای صفر که با توربینهای بادی INVELOX یکپارچه شده اند-2020 A multi-objective energy management strategy for a plus-zero energy building during a year, incorporating
renewable resources, air to water heat pump, micro-CHP, ventilation, energy storage systems and
thermal-cooling-electrical loads have been proposed in this paper. In this strategy, a novel technology of
wind turbine that has been known as INVELOX has been investigated and collaborated in ZEB planning to
reach efficient plus-ZEB at lower cost and pollution. As well the building can sell and buy power to/from
the upstream network. The total cost and pollution of the building have been considered as objective
functions. Also, the effect of objective function priority on the planning of the building has considered. To
make the results more realistic the wind speed and solar radiation of Kermanshah city in Iran have been
used. The presented problem has modeled as a mixed-integer linear programming and the Epsilon
constraint method and fuzzy satisfying approach have been used to solve and obtain the best solution.
The final results show reducing the total cost and pollution by about 34.6% and 51.2% in cost priority, also
28.7% and 54.7% in pollution priority respectively, also increment in surplus power to sell to the grid and
getting closer to reach plus-ZEB concept. Keywords: Building energy management | Fuzzy satisfying | INVELOX wind turbine | Multi-objective optimization | Plus-zero energy building | Sustainable building |

Performance evaluation for scientific balloon station-keeping strategies considering energy management strategy
ارزیابی عملکرد برای استراتژی نگهداری ایستگاه های بالون علمی با توجه به استراتژی مدیریت انرژی-2020 The combination of solar array and rechargeable battery is the main trend of energy system for scientific
balloon station-keeping, when the performances of station-keeping strategies are evaluated, energy
problem should be considered. In this paper, the performances of air ballast system and double balloon
system are evaluated with the consideration of energy management strategy. The theoretical model
consisting of thermal model, solar array power model, energy consumption model and energy evaluation
model is proposed. The energy management strategy containing solar array and lithium battery is
designed. Based on the theoretical model and energy management strategy, a MATLAB program is
developed. The feasibility is verified by comparison analysis. The energy harvesting characteristics, effects
of the station-keeping duration and effects of the station-keeping region radius are analyzed
carefully. The results show that the double balloon is superior than air ballast system from the
perspective of energy. The air ballast system requires more energy than double balloon system and the
energy difference increases over time. Air ballast system lithium battery capacity requirement is higher
than double balloon system, the total energy consumption and the energy differences decrease with
expected radius increasing. It would be helpful in selecting station-keeping strategies for scientific
balloon mission. Keywords: Energy management strategy | Lithium battery | Performance evaluation | Scientific balloon | Solar array | Station-keeping |

Peer-to-peer home energy management incorporating hydrogen storage system and solar generating units
مدیریت انرژی خانگی نظیر به نظیر با سیستم ذخیره سازی هیدروژن و واحدهای تولید کننده خورشیدی-2020 The peer-to-peer (P2P) energy management in the buildings is modeled and studied by this paper. In the
proposed P2P home energy management, the buildings share their energy resources with each other to
supply their demands. Three individual buildings are considered, two buildings are equipped with solar
panels and the other building is equipped with hydrogen storage unit. The buildings are connected to
each other by power lines for P2P operation. The uncertainty of loads and solar energy are incorporated
and the model minimizes the cost of solar unit, power lines, fuel-cell, electrolyzer, and storage tank. The
optimization problem finds optimal power of solar system, power lines, fuel-cell, electrolyzer; optimal
capacity of hydrogen storage tank; and optimal operation pattern (charging-discharging regime) of
hydrogen storage system. The results demonstrate that P2P operation helps the buildings to benefit from
their energy resources Keywords: Hydrogen storage | Load uncertainty | Peer-to-peer home energy management | Solar generating unit |

Circular economy practices within energy and waste management sectors of India: A meta-analysis
شیوه های اقتصاد مدور در بخش های انرژی و مدیریت پسماند هند: فراتحلیل-2020 Adoption of circular practices within environmental management is gaining worldwide recognition owing to
rapid resource depletion and detrimental effects of climate change. The present study therefore attempted to
ascertain the linkages between circular economy (CE) and sustainable development (SD) by examining the role
of renewable energy (RE) and waste management (WM) sectors in CE combined with policy setup and enabling
frameworks boosting the influx of circularity principles in the Indian context. Results revealed that research
dedicated towards energy recovery from waste in India lacks integration with SD. Findings also revealed that
although India is extremely dedicated towards attainment of the SDGs, penetration of CE principles within
administration requires considerable efforts especially since WM regulations for municipal, plastic and e-waste
lack alignment with CE principles. Integration of WM and RE policies under an umbrella CE policy would
provide further impetus to the attainment of circularity and SD within the Indian economy. Keywords: Circular economy | India | Policy frameworks | Renewable energy | Sustainable development goals | Waste management |

A Non-Convex Control Allocation Strategy as Energy-Efficient Torque Distributors for On-Road and Off-Road Vehicles
یک استراتژی تخصیص کنترل غیر محدب به عنوان توزیع کننده گشتاور مقرون به صرفه برای وسایل نقلیه جاده ای و خارج از جاده-2020 A Vehicle with multiple drivetrains, like a hybrid electric one, is an over-actuated system that means there is
an infinite number of combinations of torques that individual drivetrains can supply to provide a given total
torque demand. Energy efficiency is considered as the secondary objective to determine the optimum solution
among these feasible combinations. The resulting optimisation problem, which is nonlinear due to the multimodal
operation of electric machines, must be solved quickly to comply with the stability requirements of the
vehicle dynamics. A theorem is developed for the first time to formulate and parametrically solve the energyefficient
torque distribution problem of a vehicle with multiple different drivetrains. The parametric solution is
deployable on an ordinary electronic control unit (ECU) as a small-size lookup table that makes it significantly
fast in operation. The fuel-economy of combustion engines, load transformations due to longitudinal and lateral
accelerations, and traction efficiency of the off-road conditions are integrated into the developed theorem.
Simulation results illustrate the effectiveness of the provided optimal strategy as torque distributors of on-road
and off-road electrified vehicles with multiple different drivetrains. Keywords: Traction efficiency | Control allocation | Energy management strategies | Hybrid electric vehicles | Power loss | Multiple drivetrains |

Medical implications of Conducted Energy Devices in law enforcement
پیامدهای پزشکی دستگاههای هدایت انرژی در اجرای قانون-2020 This study examines the medical implications of Conducted Energy Devices (CEDs) in law enforcement, of which TASER® is the brand most recognised. In order to develop understanding of TASER® use, this study undertook both a literature review and original research using data provided by a number of UK police forces.
The comprehensive review of literature identified a range of injures, including both primary and secondary complications.
Research was conducted into TASER® use in the United Kingdom using a number of data sets, including a retrospective study of some 60,000 uses of force. This data shows TASER® was only discharged on 18% of occasions it was drawn from the holster. The injuries sustained by both subjects and Police Officers associated with TASER® use were compared and it was found that fewer injuries, as a proportion of use, were associated with TASER® than use of Police Dogs, baton, irritant spray or physical confrontation. The data examined 948 discharges of TASER® and recorded 159 attendances at the Emergency Department as a result. Only three hospital admissions were identified.
The paper concludes that the use of CEDs as a police use-of-force may be associated with injury; the overwhelming majority of such are classified as minor. Death or the more severe injuries described in the medical literature are rare and any deaths occurring within temporal proximity to the use of a CED should be investigated thoroughly and the presentation of the individual carefully recorded.
The collection of post-incident data provides evidence to the relative operational safety of the TASER® by the UK Police; it is accepted by the police that no use-offorce option is risk free, however data provided showed a greater incidence of injury to both the officers and subjects, as a proportion of use, when baton, irritant spray or physical confrontation was used. |

A novel control approach based on hybrid Fuzzy Logic and Seeker Optimization for optimal energy management between micro-sources and supercapacitor in an islanded Microgrid
یک روش کنترل جدید مبتنی بر منطق فازی ترکیبی و بهینه سازی جستجوگر برای مدیریت بهینه انرژی بین منابع کوچک و ابر رسانا در یک میکروگرید جزیره ای-2020 This work presents a novel control technique for proportional power sharing among parallel VSCs connected
to an islanded Microgrid in a distributed generation system consisting of Photovoltaic (PV) and
Solid Oxide Fuel Cell (SOFC) as two micro-sources. For tracking the maximum solar energy, a Seeker
Optimized Fuzzy based Dynamic PI (FSOA-DPI) controller is implemented for the Modified Perturb and
Observe MPPT method. Again, for the optimum cost management of the Microgrid system, DPI controller
based decentralized Virtual Impedance Drooping (VID) technique is implemented for suitable load sharing
between the two hybrid micro-sources. An Energy Storage System (ESS) regulated by FSOA-DPI controller
is also proposed for this Microgrid system to ensure the better transient and sub-transient stability
during fault occurrence. The dynamic response and stability of the system with proposed method is compared
and contrasted with conventional PI controller based method during load sharing for ensuring the
robust control under conditions of nonlinear load and faults. The harmonic analysis has been carried out
by Fast Fourier Transform (FFT) and the values indicate that the Total Harmonic Distortion (THD) is well
within the prescribed IEEE standard limits. Validation and justification of the improvements achieved by
the proposed controller are realized using Matlab/Simulink environment. Keywords: Microgrid | Distributed generation (DG) | Hybrid micro-source | Photovoltaic (PV) | Solid Oxide Fuel Cell (SOFC) | Virtual Impedance Drooping | Seeker Optimization Approach (SOA) |

Active demand-side management strategies focused on the residential sector
استراتژی های فعال مدیریت تقاضای متمرکز بر بخش مسکونی-2020 In this paper, the impact of active demand–side management strategies, including Energy Management Systems
(EMS), Photovoltaic Systems (PV) and changes in the domiciliary energy consumption habits is analyzed. In
order to perform the study, the city of Bogota and the municipality of Cajica in Colombia -South America were
selected, since, despite of their proximity, these places are exposed to different solar radiation levels. Based on
this, two photovoltaic system designs with different technical specifications were proposed to analyze their
behavior with respect to energy consumption and cost, when implemented together with a change of domiciliary
energy consumption habits in lightning circuit usage. The implementation of these strategies allows achieving
energy savings between 18 % and 27 %, according to the chosen photovoltaic system, and mainly due to changes
in the energy consumption habits of users. Likewise, the interconnected system achieves a decrease of CO2
emissions between 85 % and 86 % approximately in this circuit, making a contribution to the environmental
care. Nevertheless, the Active demand-side management (ADSM) strategy regulation is one of the challenges that
Colombian government must undertake, so the domestic user receives economic incentives that motivate him to
modify his consumption and acquire new technologies that facilitates its adoption. The implementation of this
strategies in national and international contexts may contribute significantly to a more efficient electric power
systems in general, because it starts from the active participation of residential users with elements such as their
own electricity generation. Keywords: Active demand-side management | Photovoltaic systems | Consumption habits | Energy management systems | Information management |

Transition engineering of transport in megacities with case study on commuting in Beijing
مهندسی انتقالی از حمل و نقل در شهرهای بزرگ با مطالعه موردی در مورد رفت و آمد در پکن-2020 Private automobiles have been wildly popular around the world and have transformed the concept of personal
mobility for the affluent. However, automobile-oriented development patterns have demonstrably degraded the
quality of the city environment. The economic burden of transport infrastructure asset management, plus air
pollution, CO2 emissions and congestion are pressing issues for all cities. City planners struggle with the issues of
growth in travel demand and the costs of providing traffic management, parking, policing, and emergency
services. The future of personal vehicle mobility and goods movements are particularly challenging, and it is
difficult to imagine what the sustainable solutions could be for these wicked problems of transport in megacities.
This paper explores urban form, transport activity and quality of life in future cities through the emerging
discipline, Transition Engineering. The main methodology is the Interdisciplinary Transition Innovation,
Management and Engineering (InTIME) approach, the outcome of which are innovative shift projects that directly
step down the negative factors and step up in the quality of life while maintaining the access to social and
economic activities. One shift project in Beijing is a new “Work Unit Retrofit” property development enterprise.
Integrated land use is a popular idea, but the shift projects in this research answer the questions of “how” the
transition to the future city occurs. This research demonstrates the new Transition Engineering approach to
sustainable city development that results in actionable property and infrastructure development with financial
and social benefits that can be clearly communicated to all stakeholders. Keywords: Energy transition | Transition engineering | Future cities | Work unit | Adaptive capacity | Urban form | Cycling potential | Commute model |

Managing the risks of energy efficiency insurances in a portfolio context: An actuarial diversification approach
مدیریت ریسک بیمه های بهره وری انرژی در یک زمینه پرتفوی: یک رویکرد متنوع سازی مجذوب-2020 To achieve ambitious international climate goals, an increase of energy efficiency investments is necessary and,
thus, a growing market potential arises. Concomitantly, the relevance of managing the risk of financing and
insuring energy efficiency measures increases continuously. Energy Efficiency Insurances encourage investors by
guaranteeing a predefined energy efficiency performance. However, literature on quantitative analysis of pricing
and diversification effects of such novel insurance solutions is scarce. This paper provides a first approach for the
analysis of diversification potential on three levels: collective risk diversification, cross product line diversification,
and financial hedging. Based on an extensive real-world data set for German residential buildings, the
analysis reveals that underwriting different Energy Efficiency Insurance types and constructing Markowitz
Minimum Variance Portfolios halves overall risk in terms of standard deviation. We evince that Energy Efficiency
Insurances can diversify property insurance portfolios and reduce regulatory capital for insurers under Solvency
II constraints. Moreover, we show that Energy Efficiency Insurances potentially supersede financial market instruments
such as weather derivatives in diversifying property insurance portfolios. In summary, these three
levels of diversification effects constitute an additional benefit for the introduction of Energy Efficiency
Insurances and may positively impact their market development. Keywords: Energy efficiency investment | Energy efficiency insurance | Energy portfolio risk management | Energy portfolio optimization | Risk diversification |
