区域分布式供能系统经济性概率分析
Economic Probability Analysis of Urban Distributed Energy Supply System
摘要
Abstract
In view of the coordinated supply problem of regional multi-energy complementary systems, this paper compares and analyzes different energy supply schemes.Firstly, we propose two distributed energy supply schemes: the gas turbine combined cooling heating and power (CCHP) system and environment-source heat-pump system, develop the corresponding operation strategy, and analyze the safety and environmental protection of the different energy supply schemes.Secondly, we establish a probabilistic life cycle cost (LCC) model, and present the economic calculation method of three energy supply schemes of gas turbine CCHP system, environment-source heat-pump system and traditional energy supply system.Finally, taking the commercial area of a city in the north as an example, we compare the economic efficiency of the three energy supply schemes, and obtain the the impacts of natural gas price and electricity price on the system economy through the sensitivity analysis.The result show that with the change of natural gas price and electricity price, the best economic scheme has changed, so the actual project should be combined with the specific content of the planning area and local energy prices, and the reasonable choice of energy supply system.关键词
