摘要
随着配电网中可再生能源渗透率的提高,加剧了输、配电网间的相互影响。文章提出一种基于分布式内点法的全局优化策略,利用输配电网的有限联络母线和边界节点信息,实现输配电网的分布式求解。该算法建立了输配协同动态经济调度全局模型,利用内点法求解最优条件方程,基于矩阵分裂技术完成分布式求解,其解和集中式方法一致结果。算例结果验证了所提调度方案的合理性,联合调度模型能够有效提升分布式光伏发电的利用率,分布式算法能够迅速收敛。
With the increasing penetration of distributed generators especially renewable energy resources into distribution networks,more attention should be paid to the interaction between transmission and distribution networks and an efficient rapid solution for optimal dispatch of transmission distribution coordination system is important.Thus,a global optimization strategy is proposed based on distributed interior point method.Fast distributed solution of transmission distribution coordination system is achieved with limited information exchange among boundary buses.Firstly,a global transmission distribution coordination dynamic economic dispatch model is established.Then,the optimal condition is solved by interior point method which is solved in a distributed manner based on matrix splitting technique.The distributed solution is the same as the centralized one.Lastly,the efficiency of the proposed strategy is verified by simulation.The proposed coordination model improves the consumption of photovoltaic generation and the model converges rapidly through the proposed algorithm.
