【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 brings great pressure to the peak-shaving of power system, and the application of energy storage auxiliary peak-shaving is an effective way to solve the problem of peak-shaving. However, the high cost of energy storage at the present stage limits its large-scale application. In order to give full play to the peak shaving function of limited energy storage and reduce the capacity requirement of peak shaving, this paper proposes a kind of energy storage and normal peak shaving and deep peak shaving. The practical methods of optimizing combined peak-shaving by conventional means, such as oil injection peak-shaving and starting and stopping peak-shaving, respectively, are established based on the technical indexes of annual peak-shaving insufficient probability and the calculation models of economic indexes based on annual peak-shaving cost, respectively. The technical index surface and the economic index surface of the combined peak-shaving scheme are constructed. The combined peak-shaving scheme at the intersection of the two surfaces is regarded as the combined peak-shaving optimization scheme of the power system under different levels of renewable energy permeation. For example, the regional system of photovoltaic power generation and the planned national system are taken as examples, and the optimal scheme of combined peak-shaving system under different renewable energy permeability is established and analyzed.
