Customer Directrix Load-Based Demand Response from Prosumer Communities

Demand response (DR) based on customer directrix load (CDL) is a new incentive-based DR scheme, typically invited by regional utility grid companies. In this context, a framework is proposed for a prosumer community to participate in CDL-based DR, comprising two key steps: power optimization to balance electricity costs and DR benefits for the overall prosumer community, and cost allocation for prosumers within the community through two hypothetical sub-steps, i.e., cooperation without and with DR. In the power optimization step, the Convex-Concave Procedure (CCP) algorithm is used to relax the non-convex parts of the optimization objective to be linear ones, gradually approximating the optimal solution by iteratively correcting the upper bound function. In the cost allocation step, the Owen value method is applied, which accounts for priority coalitions and eliminates the unrealistic coalition possibilities that are inherent in the calculation of Shapley value. Comprehensive simulations of a test case validate the rationality of the CDL-based DR framework and the effectiveness of the iterative method.
