“…Constraint (16) indicates that the whole power generated by the PV is sent to the load demand when the PV power is less than the need of the commercial building. When the power generated by the PV is more than the commercial building demand, the excess power will be sent to the battery energy storage or power grid.…”

“…In [15], networked microgrids are considered for a study and the optimal planning approach is examined with respect to the unpredictable nature of the generating units and load demand. In [16], in order to minimize the system risk against incident occasions, new hybrid market framework involving emergency transactions and a bilateral contract is suggested in a multi-microgrid system to parameterize the emergency energy transactions.…”

This paper aims at enhancing the resilience of a photovoltaic-based microgrid equipped with battery storage, supplying a typical commercial building. When extreme weather conditions such as hurricane, tsunami and similar events occur, leading to islanding of the microgrid from the main power grid, it is not expected that the microgrid would be taken out of service for a long time. At the same time, it is not cost effective to make the electrical system to be absolutely reliable to provide service for the customers. The main contribution of this paper lies in its ability to determine the optimal point between the operational cost and grid resilience. In other words, this work proposes an optimal management system of battery energy storage in a way to enhance the resilience of the proposed microgrid while maintaining its operational cost at a minimum level. The optimization is achieved by solving a linear optimization programming problem while the Conditional Value at Risk (CVaR) is incorporated in the objective function. The CVaR is used to account for the uncertainty in the intermittent PV system generated power and that in the electricity price. Simulation analyses are carried out in MATLAB to evaluate the performance of the proposed method. Results reveal that the commercial building microgrid resilience is improved remarkably at a slight increase in the operational cost.

Energy management systems for micro grids (EMS-MG) play an important role for optimized and stable utilizations. Microgrids (MGs) have different types of resources and loads. They can be used as a basic means for achieving improved reliability and serviceability, better power quality, and enhancing the energy efficiency. Decentralized energy management systems for micro grids (DEMS-MG) play a significant role in their optimal and stable operation. In this paper, the proposed strategy for EMS has been implemented for operation of multiple sample microgrids with renewable energy resources alongside the compound power of support such as microturbine and batteries for equalizing the mismatch between power and storage of extra energy when required. The proposed strategy is characterized by concurrent determination of responsive load based on multiagent system alongside genetic algorithm for minimizing the costs related to the microgrid operation, reducing the consumed power of different types of generated loads, and optimal production of each of the generation resources and the storage device present in the microgrid.

“…In summary, these above studies have provided guarantees for the feasibility of energy trading in microgrids. The market participation of the microgrid includes three modes: power bank model, bilateral transaction model, and hybrid model [8]. However, due to the distributed structure of the microgrid, the electricity market in the microgrid also needs to have sufficient transparency, freedom and fairness.…”

With the decreasing reserves of fossil energy and the increasing capacity of renewable energy generation, the scale of microgrid based on distributed generations is expanding. However, more operation data and transaction information of microgrids will also bring several problems: the sufficient capacity of the server in the central management needed, the crises of trust among members, the transparency of transaction information and the confidentiality of data storage. In this paper, blockchain technology is used to deal with these problems as distributed data storage technology. A double-layer framework of energy transactions based on blockchain in multi-microgrids is proposed to provide decentralized trading, information transparency and mutual trust system of each node in the trading market. The central node within the microgrid collects the demand information of the trading market in lower layer and sends them to the trading market of multi-microgrids in higher layer to seek the energy transaction. The continuous double auction mechanism is used in the trading market to guarantee free and fair transactions among nodes. The proposed transaction framework effectively reduces the transaction volume with the main grid which improves energy utilization. Comprehensive simulation results are presented to prove the feasibility of the proposed transaction framework.
