工业负荷可持续并网太阳能光伏的可行性评价

Sustainable on-grid solar photovoltaic feasibility assessment for industrial load

可再生能源发电因其间歇性而具有多变性,对发展中国家来说,可再生能源发电的成本很高。由于电价定价和机制设计不合理,上网电价和净计量等支持性政策和方案对消费者也没有太大吸引力。屋顶太阳能光伏系统自用技术可以避免这些方案的缺点,因为这种技术比公用电网的发电成本更低。因此,产消者可以以最低价格使用大部分电力,更具吸引力。本文分析了并网工业太阳能光伏发电系统的成本和可行性。结果发现,基于储能并网的光伏系统成本为0.0086$/(kW·h),公用电网将以0.062$/(kW·h)的价格出售给产消者,与使用时间评级模型相比,年能源成本将降低35.23%。此外,所提出的方案可满足96%的年能源需求,保证了供应的安全性,所提出的模型可用于其他发展中国家。

Generation of power through renewable energy resources is variable in nature due to their intermittence and the generation cost from these resources is also high for developing countries.Supportive policies and schemes like feed-in tariff and net metering are not so much attractive for consumers due to their insufficient rates and unfavorable institutional design.The shortcomings in these schemes can be avoided through self-consumption technique for roof top solar photovoltaic system,as this technique results in cheaper generation of electricity as compared to that of utility or grid.Therefore,prosumers are more attractive to use most of electrical power at cheapest price.In this paper,the cost and feasibility for the on-grid industrial solar photovoltaic system was analyzed.It is found from the results that store on-grid based photovoltaic system will be 0.0086$/(kW∙h)and utility will sell energy to the prosumers at rate of 0.062$/(kW·h),which will result in 35.23%reduction in annual cost of energy as compared to time of use rating model.Furthermore,96%of annual energy demand can be achieved by the proposed scheme,which guarantees the security of supply and the proposed model can be adopted for developing countries.
