Optimized Analysis of Operational Strategy Based on Different Optional Energy Supply Technologies in a Distributed Energy System of Buildings in Tianjin Eco-City during Cooling Season

Abstract

This paper focused on the analysis and optimization of operational strategy of No. 2 energy supply station, which is a distributed energy system, in Tianjin Eco-city, Tianjin, China. Due to the Chinese relevant policy of electrical transmission and distribution, the CHP and PV system cannot be allowed to use right now. However, with the Chinese electrical power reform, the permit of connection between distributed generation and utility is gradually released. Thus, by using the mixed integer linear programming (MILP) analyzed the operational strategy of this energy system in Tianjin Eco-city after the connection between utility and this distributed generation is permitted. Then the comparative analysis between this optimization strategy and the baseline operational strategy had been done by analyzing two factors which included economic efficiency and energy consumption.
