Research Of Regional Integrated Energy System Applied On A Scientific Innovation Harbor In Western China

The newly built urban innovation zone and other comprehensive parks are the gathering places of high energy consumption.This paper considers the organic combination of Combined Cooling Heating and Power(CCHP)and renewable energy.Facing the problem of the load changing in urban innovation zone,adding the renewable energy will further accelerate the optimization of the park’s energy supply scheduling research,so that the energy station can operate safely,economically and environmentally.The main contents include the following aspects:(1)The natural energy forms commonly used in architecture and their utilization methods and advantages and disadvantages are summarized,and the energy sources of the cold-thermal-electric trigeneration system--gas internal combustion engine trigeneration and gas turbine trigeneration are also studied in terms of operation mode and application range.(2)The paper studies the combination of these two energy modes,and points out that the recommended energy combination mode in the energy station provides theoretical and technical investigation for the selection and optimization of practical schemes in the later stage.(3)According to the early investigation of an energy station in an innovation port in the west,the hourly load of the buildings in the innovation park controlled by the whole energy station was calculated using De ST software,and load energy demand of different users is analyzed.Safety,economy and environment protection are presented.(4)The selection of different schemes.From the perspective of investors,this paper establishes an evaluation scheme of regional comprehensive energy system.According to the three indexes of technical stability,economic recovery and energy conservation and emission reduction,the internal evaluation scheme of each index is refined and dimensionless processing is conducted for each scoring scheme.Finally,the analytic hierarchy process(AHP)in operational research is used to characterize the intrinsic weight of each index,and a comprehensive energy evaluation parameter is obtained.This parameter will provide an important reference for the successful bid of the energy project.
