Abstract:

Energy storage systems co-located with renewable energy stations in industrial parks generally lack effective market-based profitability models, resulting in low utilization rates and poor economic performance. In contrast, independent energy storage operators can flexibly participate in electricity market trading. Energy storage operators that meet technical and safety standards can enhance the overall economic efficiency of multiple sub-microgrid centers within industrial parks. A coordinated optimized operation model for multi-microgrids in industrial parks, considering the participation of unified energy storage operators, was proposed. Based on factors such as power output characteristics and topological structure, the system operation architecture was constructed, and the operational modes were analyzed. K-means clustering was employed to address the uncertainties in wind and solar power output. A coordinated optimized operation model for microgrids within industrial parks was established, and the branch and bound method was applied to solve the model. Comparisons with particle swarm optimization and genetic algorithms demonstrated its advantages in solution efficiency and accuracy. The case study results demonstrated that microgrids within industrial parks, considering unified energy storage operators, could effectively increase economic benefits for both individual entities and the overall system. This approach significantly increased the revenues of energy storage operators, effectively addressed the issues of renewable energy consumption, and reduced dependence on the distribution network, providing a quantifiable decision-making basis for microgrid operation and scheduling under unified energy storage operator management.

Key words: industrial park, microgrid, integrated energy, independent energy storage operator, electricity market trading, coordinated optimization, branch and bound method, renewable energy consumption
