摘要

高比例可再生能源发电并网给电力系统调峰带来了较大压力，应用储能辅助调峰是解决系统调峰问题的有效途径，但现阶段储能的高成本限制了其规模化应用。为充分发挥有限储能的调峰作用，降低储能调峰的容量需求，文中提出一种储能与正常调峰、深度调峰、投油调峰和启停调峰等常规手段优化组合调峰的实用方法。分别建立基于年调峰不足概率的技术性指标和基于年调峰费用的经济性指标的计算模型，构建组合调峰方案的技术性指标曲面和经济性指标曲面，将两个曲面交线处的组合调峰方案作为不同可再生能源渗透水平下电力系统的组合调峰优化方案。最后，以含风电、光伏发电的区域型系统和规划的全国系统为例，制定和分析了不同可再生能源渗透率下系统的组合调峰优化方案。

Abstract

The high proportion of renewable energy generation connected with the grid has brought great pressure to the peak-shaving of electric power systems. Using energy storage for auxiliary peak-shaving is an effective way to solve this problem. However

the high cost of energy storage limits its large-scale application. To make full use of the peak-shaving function of the limited energy storage and reduce the load demand for energy storage capacity

this paper proposes a practical method to develop the combination of energy storage and normal

deep

given oil and start-stop regulation ways for peak-shaving. The calculation models of the technical index based on the probability of lack of peak load and the economic index based on the annual cost of peak-shaving are developed. The curved surfaces of technical and economic indices of the combined peak-shaving scheme are built. The combined peak-shaving scheme at the junction of technical and economic curved surfaces is the optimal one under different renewable energy penetration levels. Finally

with the regional grid and the national planning power system with wind and solar power as examples

optimal combined peak-shaving schemes under different renewable energy penetration levels are made.
