Research On Distributed Clean Energy Cooling,Electricity,Heating And Storage Multi-energy Coupling System Scheduling Strategy

With the rapid development of today’s society,energy has played an important role in the development of society.How to change the current situation of energy shortage and how to vigorously develop green energy has attracted the attention of all countries in the world.Although our country is rich in resources,my country’s industry has developed rapidly in the past ten years,and China has become one of the countries that currently consume a lot of energy,and carbon dioxide emissions have gradually increased.Along with the reform of the world’s energy structure,to promote more efficient use of energy and build a clean,environmentally friendly,low-carbon and emission-reducing energy structure,the country has also actively promoted the reform of my country’s energy structure.The multi-energy coupling system of cooling,heating,electricity and storage can realize efficient energy use.It is an integrated energy supply system of energy.It has attracted the attention of the world.While laying a good foundation for integrated energy supply,it has also become important means of driving force for the energy revolution.This article takes Tieling Logistics City G District as the system design site,and after investigating the site,it is determined that the project is feasible for the multi-energy coupling system in this area.A multi-energy coupling system of cooling,heating,electricity and storage is designed,and on this basis,the system’s scheduling strategy is studied to achieve the best strategy.This article is arranged as follows:According to the energy demand analysis of the demonstration businesses,photovoltaic power generation devices are added to the traditional cooling,heating and power supply combined system.In response to the country’s green development policy,the traditional natural gas fuel used to burn internal combustion generator sets has been replaced by light hydrocarbon gases that have achieved revolutionary innovation in recent years.It solves the single energy problem of the traditional cogeneration system and reduces pollutant emissions.And through the design of the power storage and heat storage unit inside the system,when the load changes,the system’s own energy supply regulation capability is effectively enhanced.The designed system can be applied to operating modes in different seasons,so that the system can operate more flexibly in terms of energy use,thereby increasing the nearby energy consumption capacity and making the system operate more economically.After a theoretical analysis of the feasibility of the system,the structural design of the system was carried out,and each subsystem was introduced in detail,and a reasonable selection was made according to the load parameters.The photovoltaic power generation subsystem uses the MPPT control strategy to achieve the maximum power output.Based on the processing unit and energy storage unit of the multi-energy coupling system,the corresponding optimal scheduling mathematical model is constructed,and the rapid non-dominated sorting genetic algorithm is used to contribute to the system unit under three different energy supply modes in the summer,transition period and winter.By optimization and iterative solution,the optimal solution layer of the scheduling strategy in three operating modes of summer,transition season and winter is obtained.A set of solutions was selected as the optimal scheduling strategy for this layer of solutions,and the total daily operation and maintenance costs in the three optimized modes were solved.Meanwhile,based on the same scheduling strategy,the results of scheduling when using traditional fuel and clean energy are studied,and the total daily operation and maintenance costs when using traditional energy as fuel are obtained.Through economic analysis,it can be seen that compared with the multi-energy coupling system before optimization and the multi-energy coupling system using traditional energy,the operation and management of the current energy complementary system has the lowest average daily cost of operation and management,and it is more feasible for engineering.
