基于需求侧响应的区域微电网投资成本效益分析

从投资、运营、设备寿命、碳排放等方面分析了区域微电网投资对电网企业的影响,在此基础上分别从运营成本效益、社会成本效益、用户成本效益及电网企业成本效益4个角度构建了基于需求侧响应的微电网成本效益指标,从而建立了基于需求侧响应的微电网成本效益模型,分析了微电网规划的等式及不等式约束条件,并以我国某地区需求侧响应下的微电网投资规划为例,证明了该模型的有效性和合理性。

Investment Cost-benefit Analysis of Regional Micro-grid Based on Demand-side Response

This article analyzes the impacts of regional micro-grid investment on power grid enterprises from investment, operation, equipment life, carbon emissions and other aspects. On this basis, indicators of the micro-grid based on demand-side response are built and the cost-benefit model is established from the perspective of operating cost-benefit, social cost-benefit, user cost-benefit and cost-benefit of distribution companies, respectively. Then, it incorporates demand-side response into the cost-benefit analysis of micro-grid investment, and constructs equality and inequality constraints for micro-grid planning. Finally, it chooses a case of micro-grid investment planning under the demand-side response of a certain area in China to prove validity and reasonableness of the model.
