摘要/Abstract

摘要：

可再生能源储能电站的长期稳定运行与储能系统的热量管理息息相关，合理的热量管理策略能够保障储能电站的经济性与安全性。为了合理有效地进行储能系统热量管理，本文综合电池寿命成本，以日内实时调度的最高净盈利作为优化目标，提出了考虑热量管理与电池寿命损耗成本的储能电站调度策略。并利用分片McCormick方法将双线性项精细线性化，再利用Gurobi进行快速求解，满足日内实时调度要求。案例仿真结果表明，所提模型能够兼顾热量管理与电站经济性，与传统调度策略相比具有明显优越性。且分片McCormick方法在可接受误差范围内，求解速度优于常规智能算法。

Abstract:

The long-term stable operation of renewable battery energy storage systems is closely related to the heat management of energy storage systems, and a reasonable heat management strategy can guarantee the economy and safety of the system. In order to determine a way to carry out the heat management of energy storage systems reasonably and effectively, this study proposes a scheduling strategy for energy storage power plants that considers heat management and battery life with an optimization target of high net profit in intraday real-time scheduling. It also uses the piecewise McCormick method to linearize the bilinear term and then uses Gurobi for a fast solution to meet the intraday real-time scheduling requirements. The case simulation shows that the proposed model can balance heat management and plant economy, which is significantly superior to the traditional scheduling strategy. The piecewise McCormick method offers better results than the general intelligent algorithm in terms of solution time and smaller errors.

Key words: battery energy storage system, heat management, piecewise McCormick, economic dispatch
