Study on the Optimal Dispatching Strategy of a Combined Cooling, Heating and Electric Power System Based on Demand Response

This paper proposes a combined cooling, heating and electric power (CCHP) system based on demand side response. In order to improve the economy of system, two-stage optimal scheduling scheme is proposed with goal minimizing total operating cost maximizing user satisfaction. The operation was divided into two optimization problems, including supply side. first stage, satisfaction, from new point view that users are prone excessive behavior due time-of-use electricity prices, load curves optimized. second an economic dispatch model includes costs in terms energy, maintenance environment established. An improved artificial bee colony (IABC) algorithm used solve energy production optimized stage. Case studies conducted verify efficiency method. Compared CCHP does not consider response, this method reduced typical days summer winter by 5.20% 5.76%, respectively.
