摘要
针对智能电网实际配电需求和分布式电源种类多样、波动性大等问题,设计与实现了一种基于分布式实时调度策略的智能电网控制系统。首先,构建了含柔性负荷的调度优化模型;然后,设计了一种考虑柔性负荷的智能电网经济调度策略,包括柔性负荷边际用电效益、发电组边际发电成本及功率偏差修正的分布式计算;最后,使用Matlab仿真软件分别测试了所提出的分布式调度策略在不同通信条件和不同电力元件功率约束条件下的性能。与集中式调度策略的比较结果表明,所提出的分布式智能电网调度策略具有良好的收敛性能及更优的应用前景。
In view of the actual power distribution needs of smart grid, diversified distributed power supplies and large fluctuation, a smart grid control system based on distributed real-time scheduling is designed and implemented. First, a scheduling model with flexible load is constructed. Then, a smart grid dispatching strategy considering flexible load is designed, which includes distributed computing of flexible load marginal electricity efficiency, marginal power generation cost and power deviation correction. Finally, the performance of the proposed distributed scheduling strategy under different communication conditions and power constraints of different power components is tested respectively using matlab simulation software. Compared with the centralized scheduling strategy, the results show that the proposed distributed scheduling strategy has good convergence performance and better application prospect.
