Active Distribution Networks Planning Considering Multi-DG Configurations and Contingency Analysis

This paper proposes a novel method for planning active distribution networks (ADNs) with the integration of an network management (ANM) scheme using coordinated voltage control (CVC) through on-load tap changer (OLTC) transformers. The was formulated as security-constrained optimal power flow (SCOPF) problem to minimize total operational costs, which maximizes utilization renewable distributed generators (DGs) over horizon. ANM applied OLTC ensure safe operation and reduce violations in network. To analyse impact ANM, examined both without scheme. Moreover, SCOPF, considering N-1 line contingency analysis multi-DG configuration, implemented feasibility proposed advantages under situations. validated on weakly-meshed 16-bus UK generic system (UKGDS). results showed that can lower costs maintain feasible conditions even case contingency. mitigated rise effect caused by DGs maximized their utilization.
