摘要：

针对传统电网综合能源规划中未考虑柔性负荷(FL)的问题,提出一种利用FL“虚拟储能”特性与电网综合能源协调规划的方法。首先,通过构建FL转移和削减两种响应模型,优化负荷曲线;其次,从电网经济性、电能质量和供需能力等多角度构建了电网扩建规划评估指标体系,进而实现电网最优扩建年限计算。最后,通过对10 kV 37节点实际配电网进行仿真,其结果表明,电网负荷分布和FL分布对电网规划具有延缓作用,能改善电网末端电压和提高运行经济性。

关键词: 综合能源规划, 柔性负荷, 响应模型, 扩建评估指标

Abstract:

Aiming at the problem that flexible load (FL) is not considered in the integrated energy planning of the traditional power grid.A method of using FL "virtual energy storage" characteristics to coordinate planning with integrated power grid energy is proposed.First,optimize the load curve by constructing two response models of FL transfer and reduction;secondly,construct a grid expansion planning evaluation index system from multiple perspectives such as grid economy,power quality and supply and demand capabilities,and then realize the calculation of the optimal expansion life of the grid.Finally,through the simulation of the actual distribution network of 10 kV 37 nodes,the results show that the distribution of grid load and FL distribution have a delaying effect on grid planning,and can improve the terminal voltage of the grid and increase the operating economy.

Key words: integrated energy planning, flexible load, response model, extension evaluation index
