| contents | Community battery systems have been widely deployed to provide services to the grid. Unlike a single battery storage system in the community, coordinating multiple community batteries can further unlock their value, enhancing the viability of community battery solutions. However, the centralized control of community batteries relies on the full information of the system, which is less practical and may even lead to privacy leakage. In this paper, we formulate a value-stacking optimization problem for community batteries to interact with local solar, buildings, and the grid, within distribution network constraints. We then propose a distributed algorithm using asynchronous distributed alternate direction method of multipliers (ADMM) to solve the problem. Our algorithm is robust to communication latency between community batteries and the grid while preserving the operational privacy. The simulation results demonstrate the convergence of our proposed asynchronous distributed ADMM algorithm. We also evaluate the electricity cost and the contribution of each value stream in the value-stacking problem for community batteries using real-world data. |
