Abstract
Energy storage power station is an indispensable link in the construction of integrated energy stations. It has multiple values such as peak cutting and valley filling, peak and valley arbitrage. This article analyzes the positioning of energy storage function. Then, taking the best daily net income as the objective function, along with the main transformer satisfying N-1 principle, conservation of energy storage charge and discharge capacity, etc. as constraints, the capacity planning model of multi-site fusion energy storage capacity is constructed, taking multiple values into account, and propose the process of a genetic algorithm model solution. Finally, through carrying out capacity optimization for typical multi-site fusion energy storage, the effectiveness of the model and method is verified. The method in this paper can effectively guide multi-site integrated planning and design.
