Survey of Optimization Models for Power System Operation and Expansion Planning With Demand Response

With the implementation of demand response programs and its increasing penetration in the power grid, various new challenges to the grid’s operation have emerged. As a consequence, optimizing the operation of the power grid and the allocation of demand response resources, in the short-term, medium-term and long-term, has become a fundamental problem. This survey presents a review of the optimization approaches in the literature for the integration of DR in three central problems in power systems planning, namely optimal power flow, unit commitment, and generation and transmission expansion planning. We also highlight important future research directions.
