Abstract
The generation unit aggregation is frequently used in a virtual power plant which participates in real-time spot markets. In this letter, an analytical method is proposed to quickly and precisely compute a piecewise quadratic function of aggregated units. Three propositions are introduced and proven in the letter in order to guarantee the accuracy of the equivalent model after aggregation. Numerical results verify the validity of the proposed method.
