Research On The Allocation Of Resources For Hot And Cold Electricity Microgrid Stoush With Economy As An Indicator

The microgrid can optimize energy allocation and improve resource utilization.It is a resource-saving and environment-friendly system.It can improve the increasingly fragile ecological environment and increase energy efficiency by relying on clean energy such as natural gas,light energy and wind energy.The CHP system is a cascade energy interconnection system that combines refrigeration,heating and power generation processes into a microgrid system.Effective use of all kinds of clean energy,reasonable optimization of the output of each micro-source,can better allocate resources to maintain optimal operating conditions.According to the fuel gas electricity generation,the light bend down the electricity generation,the wind power generation and the electrical energy memory and so on the micro power source principle and the movement characteristic,has carried on the elaboration to the system composition,establishes the cold thermoelectricity to pay proportional to production the micro electrical network system the mathematical model,and determines this micro electrical network system the disposition plan.Then selects the grain of subgroup algorithm,to the mathematical model which establishes carries on the solution.Take the year total expense,an energy use factor and an energy save rate as the optimized goals,considered separately in “decides the electricity by the heat” “to decide the heat by the electricity” under the pattern as well as the mix pattern which unifies both carries on the comparative analysis,obtains the most superior movement strategy and the power distribution,to optimizes the result from the energy conservation,the efficient angle carries on the contrast analysis,through supplies the system to the score,the optimization control method which this article proposed to this kind of micro electrical network system operating efficiency to have certain promoter action.At the same time,in view of now the energy situation,the micro electrical network usability and the feasibility which develops vigorously,in the efficient aspect,through the overall evaluation association for the system movement cost,the economy which this article establishes and the energy conservation direction micro electrical network system mathematical model,and satisfies under the correlation constraint condition after the mathematical model grain of subgroup algorithm the solution,obtained has conformed to the economical,the energy conservation standard mix pattern movement plan.Through and divided an inheritance the system to carry on the contrast,reduced an energy consumption,an energy saved rate is 6.36%.
