摘要
灵活可拓展的电压控制策略在含有多个分布式电源、且电源和负荷均不断变化的配电网具有重要意义。着眼于智能配电网的发展需求,提出一种基于案例式推理技术的分布式智能电压控制策略。通过自动感知网络电压波动,在保证系统安全和清洁能源输出比例的情况下,即时提供电压控制策略并建立完备的具有自学习能力的案例库。以包含多个分布式电源的10 k V配电网为实例,对所提出的电压控制策略进行实时数字仿真,结果证明该控制策略能有效解决网络中的电压波动问题。
The design of voltage control strategy for distribution networks with multiple distributed generation （DG） schemes should concentrate on reliability, flexibility and extensibility. A distributed voltage control strategy utilizing case based reasoning （CBR） is proposed in this paper. It has the potential to deliver the future active distribution vision, in a way that maintains power quality whilst also accommodating significant levels of DG penetration. This paper presents real time test arising from the application of the voltage control strategy on an existing 10 kV network. The testing results show that the CBR system has the capability to maintain voltages within statutory limits effectively.
