An Optimized Dispatch Approach for Hybrid DC Grid System Considering Multi-dimensional Constraints
摘要
Abstract
Hybrid DC grid technology is one of key solutions dealing with large-scale renewable energy integration and consumption, and a reasonable dispatch decision can optimize the operation security and economy. This paper presented an optimized dispatch approach for hybrid DC grid system considering multidimensional constraints. Firstly, according to the different topologies and a variety of operation control modes, the nodes were classified and standardized, then a general hybrid DC network model was developed; Secondly, the voltage deviations corresponding to different node types were described and the power flow of the hybrid DC grid was solved based on Seidel Gauss method; Finally, considering the multidimensional constraints of the DC network, the nonlinear programming method was used to obtain the optimal dispatch decision and minimize the overall loss. To verify the presented approach, the dispatch orders for different hybrid DC grid schemes were calculated and optimized. The results show that the optimized dispatch orders enable the hybrid DC grid operating within acceptable range and minimum power loss, which means the improved security and economy.关键词
