摘要

摘要: 针对电池储能系统应用于电网侧削峰填谷时的配置和出力优化问题，研究了一种综合考虑储能经济性及削峰填谷效果的优化模型。将储能系统的投资成本、运维成本、分时电价收益、政策补贴换算到天，作为经济性指标；将储能接入前后的负荷峰值变化作为调峰效果的评价标准，储能接入后的负荷曲线标准差作为平滑负荷曲线效果的评价标准，两者量化后作为储能系统带来的社会效益的表征。通过线性加权将多目标优化问题转化为单目标优化问题后，设定客观约束，在MATLAB中使用YALMIP工具包进行求解。通过算例求解，给出了不同量化系数、加权系数下的储能系统优化容量、额定功率及日出力，总结出了储能系统功率容量比的理想值，得到了优化计算结果与优化目标计算过程中的量化系数和加权系数之间的关系。

Abstract: This paper studies an optimization model that comprehensively considers the energy storage economy and the effect of peak shaving and valley filling, aiming at the configuration and output optimization problems of battery energy storage system when it is applied to grid side peak shaving and valley filling. This paper converts the investment cost, operation and maintenance cost, time-of-use electricity price benefit, and policy subsidies of the energy storage system into days as economic indicators. This paper takes the standard deviation of the load curve after the energy storage is connected as the evaluation standard for the effect of smoothing the load curve, and both of which are quantified as the characterization of the social benefits brought by the energy storage system. The multi-objective optimization problem is transformed into a single-objective optimization problem through linear weighting, then objective constraints are set, and the YALMIP toolkit is used to solve the problem in MATLAB. The optimal capacity, rated power and daily output of the energy storage system under different quantization coefficients and weighting coefficients are given through the calculation example. The ideal value of the power capacity ratio of the energy storage system is summarized, also the relationship between the optimization calculation results and the quantization coefficients and weighting coefficients in the calculation process of the optimization target is analyzed.
