Hybrid controller of energy storage and renewable DG for congestion management

Abstract

High penetration of renewable energy resources in distribution networks might lead to congestion issues in some corridors (lines) of the existing circuits, primarily during minimum demand scenarios. The adoption of active network management (ANM) schemes can effectively manage the power output of renewable distributed generation (i.e., curtailment) to prevent thermal constraint violation. However, this approach results (as expected) in lower contributions of low-carbon electricity generation to the system, hence lower revenues. By incorporating energy storage systems, wind farms could improve their capacity factor. Energy storage systems can be used to deal with congestion issues, leaving cu..
