Abstract:
The operation mode of gas turbine(GT) in the traditional combined heat and power dispatching greatly limits the peak-shaving capability of the system. A method for optimal dispatch of concentrating solar power(CSP) station participation in heating is proposed. The thermal inertia of the heating network and heating area in the scheduling process is considered. First, a model for the CSP station to participate in the electric heating combined system regulation is built to enhance the peak-regulation capability of the source-side gas turbine unit. Secondly, the thermal inertia model of the heating network and building clusters is constructed, the potential of virtual energy storage is tapped, and the coordinated and optimized operation of the two types of thermal inertia and the CSP station is realized under the conditions of satisfying various constraints. Five comparison scenarios are constructed in the simulation analysis to verify the effectiveness of the coordination between the thermal inertia of the heating network and heating area and the heat storage system of the CSP station in improving the operating economy of the system, improving the efficiency of wind power and reducing the carbon emissions of the system.
