Development of Aggregation Models to Analyze the Impact of Virtual Power Plant Operation on the Distribution Network

Accelerating worldwide energy transition trends and the continuous proliferation of renewable energy facilities have exacerbated energy volatility and compromised system stability. Accordingly, this paper proposes an aggregation model for selecting resources to output by integrating generation-type resources and demand-type resources, and grouping resources according to sensitivity. Implemented using the OpenDSS-Matlab interconnection system, the accuracy of the model was validated through an analysis of its effects on distribution system voltage stability. © The Korean Institute of Electrical Engineers.
