چکیده انگلیسی:
This paper presents a hierarchical energy management system (HEMS) for multiple home energy hubs in the
neighborhood grid (MHEHNG). The main objectives are maximizing financial profit and shaving the peak of
upstream grid. This way, the proposed HEMS manages the energy generation and energy storing, as well as
energy purchase/sale of each home energy hub (HEH) under the two levels including lower and upper levels. The
lower level is responsible for supplying the internal load and reducing the energy cost in each HEH. The upper
level is the central energy management system (CEMS) which is focused on forming a coalition between the local
HEHs, as well as giving the tempting offers to increase the financial profit through a heuristic bidding strategy.
The principle of proposed bidding strategy is based on weighted distributing of excess power among consumers
that is one of the contribution of this paper. It leads to trading more energy at the lowest possible price.
Determining the most appropriate operational scenario in each HEH requires the investigation of both technical
and financial aspects. A novel scenario selector method has been proposed based on SOC-tariff plane. This is
another contribution of this work. A simulator has been implemented in the MATLAB/GUI software environment
to facilitate the evaluation of proposed HEMS performance. The simulation results indicate the effectiveness of
the proposed HEMS. They show a decrease in the total energy cost of the CBs by almost 9.4%, and an increase in
the total profit of the HEHs by 4.55%. Also, it was found out that the energy can be purchased from HEHs at
varying rates and can be sold to the consumers at almost constant rates by using the proposed bidding strategy.
This motivates HEHs to submit more power at lower tariffs to the CEMS.
