ADMM-Based Energy-Reserve Joint Dispatch Considering Cross-Zone Reserve Dispatchability

Abstract

As distributed energy resources (DERs) becomes widespread in power system, distributed algorithms are required for economic dispatch. Renewable generators accrue along with the randomness and volatility of the generation side, therefore higher proportion of reserves are applied in the system for stability concerns. Zonal-partitioned reserve dispatch is commonly considered in large-scale reserve dispatch cases. This paper gives solution to energy-reserve joint dispatch problems concerning reserve cross-zone dispatchability by modified ADMM algorithm. The precision and economic-effectiveness of the algorithm is validated through case studies based on IEEE 30-bus system.
