Modeling of demand response in California ISO market systems

This paper describes the implementation of demand response (DR) program in CAISO. A Participating Load Pilot (PLP) program has been implemented in CAISO system during summer 2009. This is the first time that a cross-section of residential, commercial and industrial customers has been in the PL (Participating Load) program and modeled in CAISO systems. This paper takes this Participating Load Pilot (PLP) as an example to describe the DR modeling of CAISO market system. It discusses the integration with various CAISO internal and external applications. The paper also describes the challenges and experiments of the DR Program in CAISO EMS and market application systems. A future development of Proxy Demand Response (PDR) program in CAISO market systems is also discussed.
