Research On Operation Model And Benefit Evaluation Of Integrated Energy System Project Development

Integrated Energy System(IES)is able to integrate and collaboratively optimize multiple kinds of energy including electricity,heat,gas,water,and its core is the complementation between different kinds of energy from time and space.On one hand,IES will coordinate the energy supply and demand as well as making good use of renewable energy so as to reducing the fossil fuel energy utilization.On the other hand,the cascade utilization of energy and comprehensive energy efficiency improvement should be realized using IES.Under the background of energy-saving and emission-reduction,the development trend of energy system is now changing to exploiting the complementary potential and to achieve the comprehensive utilization and optimization.IES is the key to solve the problems above and improve the energy consumption,economic cost and environment benefits.For now,there are several business and construction modes to carry out the IES projects,how to choose the suitable business mode based on mode analysis is now becoming a hot research topic.This paper first analyzes the complementary operation theory and the basic feature as well as basic components of IES based on related research status at home and abroad.Second,the business mode of IES has been summarized in detail including financing requirement,user scale and service mode.Third,the IES equipment model including photovoltaic generation,gas turbines were designed.Besides,energy storage devices model including storage battery,cool storage,heat storage and flywheel energy storage were built as well as other auxiliary devices.The comprehensive benefit optimization model of IES and related particle swarm optimization method were proposed.At last,the comprehensive benefit index system of IES’s business mode was designed and its data can be calculated through the optimization model.The most suitable mode can be derived after the calculation of TOPSIS model.
