A Robust Aggregate Model for Multi-Energy Virtual Power Plant in Grid Dispatch

This paper proposes a model for the aggregation problem of a multi-energy virtual power plant participating in day-ahead energy markets. The virtual power plant comprises various multi-energy conversion equipment, renewable units and energy storage. The proposed model considers the uncertainty associated with the dispatch signals from the system operator. The resulting model is heuristically modified by solving a series of robust optimization problem to guarantee any possible dispatch signals which satisfy the proposed model can be realized. Results from a case study illustrate the effectiveness of the proposed approach.
