Study on sustainable development of wind farm based on energy synthesis

Existing"investment"and"income"of wind power industry are asynchronous,thus,a comprehensive evaluation method is needed for assessing the sustainable development of wind farm.Solar energy synthesis theory was proposed,and five quantitative indicators were adopted for analyzing the sustainable development degree,including EYR,ELR,EIR,ESIand PR.The integrated energy value system diagram was obtained by energy flow classification,after generating the energy system diagram of wind farm.Taking Aand B wind farm as examples,the calculation of energy value indicates that the energy conversion rate of Bis lower than that of A,and B wind farm appears higher production efficiency.Although the ESI value of Bis higher than A,decreasing the ELRvalue and increasing the EYRvalue are the same path for two wind farms,to further improving the sustainable development ability.
