Abstract:

Increasing penetration of distributed energy technologies presents challenges and opportunities for distribution companies. On one end, uncontrolled DER (Distributed Energy Resources) will threaten the stability and reliability of the distribution grid, on the other end, properly monitored, controlled and optimized DERs can aid the reliable operation of the distribution system. The Distributed Energy Resources Management Systems (DERMS) is a computational tool capable of optimizing, controlling, and managing the operation of multiple DER connected to the power distribution grid to provide reliability, flexibility, and increased quality of power supply service. Through DERMS it is possible to aggregate dispersed DER to coordinate the dispatch of electricity in the network from technical, economic, and strategic factors. This work presents results from a project of distributed energy resources integrated into the operation center of a Brazilian distribution company. The main challenges in planning and operation of distribution networks with high penetration of DER are discussed. Tests results based on a site deployment in a 13.8 kV distribution feeder with two storage systems with a total capacity of 1,150 kW / 1,750 kWh and a solar power plant with 1.4 MWp are presented.
