1 A multi-objective voltage stability constrained energy management system for isolated microgrids
یک سیستم مدیریت انرژی با ثبات ولتاژ چند هدف محدود شده برای ریز شبکه های جدا شده-2020
Nowadays, microgrids are more likely to operate in an isolated state, and it is of outmost importance to consider various security issues in the management of such systems. This paper proposes a new energy management system for isolated microgrids, which considers the voltage stability and generation contingency constraints.A multi-objective security constrained microgrid energy management system (MOSC-MEMS) based on a coordinated unit commitment-optimal power flow (UC-OPF) framework is introduced, aiming at minimization of real power losses, voltage deviations, and power generation costs. A Pareto optimal front is obtained using the -constraint method, and the best compromise solution is derived using the Fuzzy Satisfying criterion. Furthermore, a CIGRE benchmark test system based on European medium voltage network is used to demonstrate the performance of the proposed MOSC-MEMS. The simulation results, obtained by implementing the proposed framework in general algebraic modeling system (GAMS), indicate the feasibility of the proposed model and imply the significance of security constraints in the microgrid energy management systems

2 Peer-to-peer energy bartering for the resilience response enhancement of networked microgrids
مبادله انرژی نظیر به نظیر برای افزایش پاسخ مقاومت درستی از ریز شبکه های شبکه شده-2020
This paper proposes a peer-to-peer (P2P) energy bartering framework for enhancing resilience response of networked microgrids (NMGs) against extreme events. In the emergencies, electrically isolated microgrids (MGs) are physically interconnected via a common bus to form NMGs for energy sharing. These MGs communicate with each other through cyber links to reach a consensus on direct energy bartering among themselves. The proposed energy bartering framework allows an unlimited number of MGs to share energy in the networked mode with less adoption of new regulations for P2P energy sharing management and without need to financial instruments and the intermediacy of any financial and central energy management agent. This framework is implemented in two stages. First, each MG individually maximizes its exported power for enhancing resilience response of NMGs by holding individual rationality constraint which guarantees that MGs operation costs in P2P energy sharing will not exceed than when they do not participate. Then, by exploiting an average consensus algorithm and proportional sharing assumption, each MG determines its imported and exported power in a decentralized way. Numerical results demonstrate the effectiveness of the proposed framework for enhancing the overall resilience of NMGs, while by preserving individual rationality constraint, MGs prefer P2P networked operation mode rather than individual operation mode.
