UK Power Networks Providing Power Services from Distributed Energy Resources to Transmission System Operator via a Centralised DERMS platform

Abstract

The DERMS platform is a centralised control system that enables distributed energy resources (DER) connected to the distribution network to provide services to the transmission grid, in a coordinated and controlled manner. This paper presents the simulation results obtained from testing the functionality of the DERMS when providing real and reactive power services to the Electricity System Operator in UK, National Grid. The simulation results show that the DERMS effectively determines DER availability, capabilities and costs, and translate them into service availability and cost to National Grid at the interface GSPs, while optimising the DNO network. The DERMS real-time algorithm is shown to successfully provide coordinated services to National Grid from DER, in a pre-production simulation environment. This new control approach can create additional revenue streams for DER, hence facilitating DNO transition to the DSO business model.
