综合能源服务对居民小区负荷特性的影响研究

Study on the Impact of Integrated Energy Services on Load Characteristics of Residential Quarters

随着综合能源服务业务的深入开展,未来将有大量的分布式能源接入电网,电动汽车、储能、微电网等柔性负荷与电网的互动也会越来越频繁,这些综合能源服务对电网负荷特性的影响越来越大。首先分析了一居民小区常规负荷特性;其次利用蒙特卡洛模拟方法得到电动汽车充电负荷特性曲线,并给出光伏发电功率曲线及用于削峰填谷的储能容量配置;最后分析了电动汽车、光伏发电、储能系统的接入对电网负荷特性的影响。这对于指导新形势下的负荷预测、电网规划和建设具有一定的指导意义。

With the in-depth development of integrated energy services, a large number of distributed energy will be connected to the grid in the future, and the interaction between flexible loads such as electric vehicles, energy storage, micro-grid and the grid will become more and more frequent. These integrated energy services have more and more influence on the load characteristics of the grid. Firstly, this paper analyzed the conventional load characteristics of a residential area. Secondly, it obtained the load characteristics curve of EV by Monte Carlo simulation method, and gave the power curve of photovoltaic power generation and the allocation of energy storage capacity for peak shaving and valley filling. Finally, it analyzed the influence of the access of EV, photovoltaic power generation and energy storage system on the load characteristics of power grid. This is of great significance for guiding load forecasting, power grid planning and construction under the new situation.
