Integrating Heterogeneous Demand Response into N-1 Security Assessment by Multi-Parametric Programming

With the rapid growth of distributed energy resource integration, the power system is facing increased challenge of operation security. Demand response, as an underutilized resource, has shown great potential to support system security. This paper proposes a novel scheme to integrate heterogeneous demand side resources in the N-1 security assessment, which contains two steps: demand feature compression and joint scheduling with demand response. The general control model is formulated by multi-parametric programming to analyze various demand response resources and eliminate the privacy concerns. Cases studies validate the efficiency of proposed method, showing the underlying benefit of demand side participation.
