基于状态势博弈的电力系统分布式经济调度方法
A STATE-BASED POTENTIAL GAME APPROACH FOR DISTRIBUTED ECONOMIC DISPATCH
未来电网中出现的主要变革之一在于电力系统电源结构的变化,分布式能源发电设备的广泛接入给传统调度与控制框架带来了严峻挑战.电力系统尤其是主动配电网中,调度控制体系的去中心化成为一种趋势.状态势博弈理论为电力系统分布式调度与控制体系的构建提供了一个良好框架.文章基于状态势博弈理论,给出了分布式电力系统经济调度的一般设计方法.该方法能够兼顾全网功率平衡约束与网络传输功率限制,同时实现主体间通信量极小化,因而具有较强的算法鲁棒性与实际应用价值.通过IEEE 9节点标准系统的仿真分析验证了所提方法的有效性及正确性.
One of the main revolutions of the future power gird is the change of power source structure. The wide-spread integration of distributed energy resources bring severe challenges to the traditional dispatch and control framework. Cetre-free dispatch and control mechanism has become a trend for power system, especially active distribution network. State based potential game provieds a proper framework for establishing this mechanism. This paper studies a general design approach for distributed economic dispatch, which could not only tackle both the power balance constraint and power flow transfer limits, but also entail low communication and exchanged information, therefore it possesses robustness to the environment uncertainties and has values for engineering applications. Numerical studies based on IEEE 9 bus system has been verified the correctness and effectiveness of this approach.
