摘要
随着新型电力系统的构建,新能源大规模开发会造成严重的电力系统新能源消纳能力不足和电力电量平衡问题,配置合理规模的储能可显著缓解该压力。基于自主研发的含网架约束以及分区联络线交易约束的时序生产模拟软件,研究了考虑多分区考核目标差异的省级电网储能规划方法。首先,介绍了时序生产模拟软件的算法框架,然后,基于该软件,在考虑分区考核目标差异和分区联络线交易约束的前提下,提出了以储能投资成本最小为目标函数的各分区储能容量配置优化方法。最后,针对西北某高比例新能源接入的省级电网规划场景进行算列分析和敏感性分析,验证了所提方法的合理性和实用性。
With the construction of a new power system, the large-scale development of renewable energy will lead to a seriously insufficient utilization rate of renewable energy and balance problems of power and electricity, which can be significantly alleviated by configuring a suitable energy storage system(ESS). In this paper, an ESS planning method considering the difference of multipartition assessment objectives for provincial power grids is studied based on a self-developed time series production simulation software that contains power system structure and tie-line transaction constraints. Firstly, the algorithm framework of the time series production simulation software is introduced. Then according to this software, an optimal configuration method for energy storage capacity is proposed, with the minimum investment cost of energy storage as the objective function, after considering the differences in assessment objectives and tie-line transaction constraints of each partition. Finally, calculation and sensitivity analysis are performed on a planned provincial power grid integrated with renewable energy with a high proportion in northwest China, which verifies the rationality and utility of the proposed method.
