摘要
随着分布式电源接入配电网逐渐增多,其对分布式电源和配电网的成本效益产生了影响。在总结了当前分布式电源并网的商业模式的基础上,采用净现值法和投资回收期法从配电公司和独立投资商两个方面对分布式电源接入后配电网的成本效益进行了计算和分析。比较了不同商业模式和不同负荷大小下分布式电源并网的成本效益的不同。计算表明当前商业模式下分布式电源接入从经济上来说对配电公司是不利的,独立投资商自用发电比例越大收益越多。
The gradual increase of the distributed generation connected to distribution network has exerted an impact on the cost and benefit of the distributed generation and distribution network. On the basis of summarizing the current business model of grid-connected distributed generation, this paper calculates the cost and benefit of power company and independent investor after distributed generation connected to distribution network with using net present value method and payback period method. And then the paper compares the cost and benefit of grid-connected distributed generation under different business models and different load mode. The calculation results show that, in the economic aspect, distributed generations bring more disadvantage to power company under the current business models, and independent investors gain more benefit when using more power.
