A Novel Energy Management in Dynamic Large Scale Distribution Network Reconfiguration Integrated by Energy Storage Systems

摘要

Penetration of renewable energy sources (RESs) and electrical energy storage (EES) systems in distribution systems are increased, and it is crucial to investigate their impact on system operation scheme, systems' reliability and security. In this paper, energy not supplied (ENS) and voltage stability index (VSI) of distribution networks are investigated in dynamic distribution network reconfiguration including RESs and EES systems. The optimal charge/discharge scheme for EES systems and optimal distribution network topology are presented in order to optimize the operational costs, reliability index and security index, simultaneously. Finally, the proposed strategy is applied to a large-scale 118-bus IEEE distribution test network in order to show the economic justification of proposed approach.
