| 英文摘要 |
| User-side distributed energy storages are potential high-quality resources for frequency modulation in the
power system. However, their idle time and idle power are under poor utilization. This paper takes distributed energy
storage cluster as the research object, and designs a completely distributed collaborative control algorithm based on the
state potential game theory so as to promote distributed energy storage aggregation to participate in the primary frequency
modulation of the power system. To adapt to the situation that distributed energy storage frequently exits/participates in
frequency auxiliary services, this paper first turns the problem into a state potential game, then establishes the distributed
storage behavior logic and their interaction mechanism. By this way, distributed energy storages can adjust their strategy
dynamically through interactions, eventually the overall unit regulated power of distributed energy storage cluster is kept
as constant. Finally, a simulation of AC microgrid is given, which proves that the distributed energy storage cluster based
on this algorithm can effectively enhance the frequency stability of power system. |
