Abstract:Based on the life cycle analysis method of integrated energy project and considering the optimal dispatching strategy of system operation, an economic evaluation method is proposed with integrated energy coordination and optimal dispatching model and full life cycle economic analysis model together, including gas turbine, boiler, fan, photovoltaic, electro-thermal energy storage, electric load and thermal load, which solves the problem of extensive economic analysis and estimation in comprehensive energy planning and designing. Taking CHP-type integrated energy system of a park in Chongqing for example, the effectiveness of the proposed economic evaluation method is verified through the analysis of energy supply dispatch and economic indicators. The results show that the economic evaluation method of integrated energy system based on the proposed optimal operation simulation can greatly improve the accuracy and flexibility of economic analysis of integrated energy planning and designing, and can better evaluate the rationality and operability of the system scheme.
