Abstract:

To ensure the economy and stability of microgrid operation, the power fluctuations of renewable energy source (RES) and the lifetime characteristics of battery energy storage system (BESS) should be considered. The influence of charging and discharging depth and rate on the lifetime of BESS is researched, a model of battery energy storage system for real-time optimal scheduling is established, and thealternating direction method of multipliers is adopted for the distributed optimal scheduling of microgrid clusters. The distributed optimization method does not require any global information and can protect the privacy of microgrid in the maximum extent . Simulation results show that the proposed method can make the energy storage battery operate in a high SoC and still can make the system stable and reliable in case of communication failure.

Key words: microgrid cluster, energy storage battery life, alternating direction method of multipliers, distributed optimization, communication failures
