PHEV的随机充电行为会对配电网造成如电压越界、网损增大等直接影响,为了降低PHEV并网对电网产生的影响,提出一种基于区间算法的优化充电方案。方案通过用户侧与配网侧的互动,采集相关数据;利用基于区间算法的前推回代模型,将负荷本身的波动性考虑到方案中,进行充电行为分析;经过安全稳定性校验,输出相应的PHEV接入方案。以IEEE 33标准节点系统为算例,验证了智能充电方案的可行性。
The random charging behavior of PHEV will directly affect the power distribution network such as the voltage over-voltage and the network loss increase. In order to reduce the impact of PHEV power grid on the power grid, an optimal charging scheme based on interval algorithm is proposed. Through the interaction between user side and distribution network side, the program collects relevant data. Using the pre-push back-substitution model based on interval algorithm, the volatility of the load is taken into account in the scheme to conduct the charging behavior analysis. After the safety and stability verification, the output Corresponding PHEV access plan. Taking IEEE 33 standard node system as an example, the feasibility of intelligent charging scheme is verified.
