Abstract

Abstract:

An optimal allocation model for the planning of energy storage systems considering power interconnections is established for multi-storage system planning in multi-area grids to accommodate the gradual increase in the scale of renewable energy. First, an equivalent model of a multi-region power system is proposed to clarify the cooperation of interconnected regions; second, the unit start-stop planning method in a multi-region system is proposed to calculate the intraday start-stop scheme of units subordinated to different regions. Subsequently, a two-layer planning model of energy storage systems for multi-area grids considering power interconnections is proposed to allocate storage systems in interconnected grids. The optimal renewable energy consumption of the entire grid is considered as the outer layer objective to calculate the configuration of the energy storage systems. The inner model is developed to minimize the sum of the fluctuations of the intra-regional transmission power and the injection power in each region for the optimal operation (including thermal units, storage systems, and transmission lines) of multiple regions and scenarios. Subsequently, the approximate network loss value and utilization index of the transmission lines are proposed to quantify the benefits of the energy storage planning scheme. Finally, we verify the effectiveness of the proposed model and method through a case analysis. The results show that the proposed model can fully consider the requirements for renewable energy consumption in each region and effectively improve the consumption index of the entire grid, which can be applied to the collaborative planning of energy storage systems in a wide-area interconnected grid.

Key words: planning of energy storage system, optimal operation, interconnected grids, renewable energy consumption
