as an effective way to promote new energy consumption
are becoming the current research hotspot. In order to explore effective approaches to power interaction between different subjects within the microgrid under the situation of green and low-carbon transformation of energy structure and the reform of the electricity market
and to fully utilize the regulatory potential of energy storage as an independent subject participating in power trading
this paper proposes a coordinative optimization strategy based on the hierarchical nested game of independent energy storage and supply-demand dual-response in microgrids. Firstly
based on the flexible adjustment of source-storage-load
a two-level nested game interaction framework is constructed for multiple subjects in the microgrid
in which the first-level game is the optimization of energy consumption strategy for photovoltaic users' demand response
and the second-level game is the optimization of microgrid's energy supply strategy through the coordination of independent energy storage
achieving dual-response of supply and demand through the interaction of decision variables at two-level. Secondly
according to the source-storage-load hierarchical nested framework
a distributed collaborative optimization model considering the interests of various market participants is established. Then
the heuristic algorithm combined with the mixed integer programming method is used to solve the interaction strategies of supply and demand multiple participants in pursuit of the optimal objective. Finally
the effectiveness of the proposed strategy was rerified through numerical examples
i.e.
it can effectively balance the interests of multiple subjects
improve the utilization rate of energy storage resources
optimize the balance between supply and demand of microgrids
and achieve an improvement in overall economic benefits.
