基于需求侧响应的广义储能容量配置方法研究

Research on generalized storage capacity allocation method considering demand side response

微电网作为新能源消纳的有效形式,对风光资源的消纳产生了重要的促进作用。但是,由于风光发电的不确定性以及波动性,导致微电网内部弃风弃光以及失负荷问题严重。广义储能结合需求侧资源及传统储能的双重优势,为解决上述问题提供了新思路。因此,本文提出一种考虑需求侧响应的广义储能配置方法。本文介绍了广义储能的模型,建立了广义储能配置的双层模型。模型上层以惩罚成本最小为目标,发挥需求侧资源的优势,降低微电网弃风、弃光及失负荷功率;在上层的基础上,下层以微电网净现值最大为目标,得到广义储能的配置方案。通过对3种不同策略的比较,证明了需求侧参与响应时,可实现用户与电网的双赢。

As an effective form of new energy absorption,micro-grid plays an important role in promoting the absorption of wind-solar resources.However,due to the uncertainty and fluctuation of wind and solar power generation,the problem of wind abandonment and load loss in micro-grid is serious.Generalized Energy Storage combines the double advantages of demand-side resources and traditional energy storage,and provides a new way to solve these problems.Therefore,a generalized energy storage allocation method considering demand side response is proposed.Firstly,the generalized energy storage model is introduced.Then,a two-layer model of generalized energy storage allocation is established.The upper layer aims to minimize the penalty cost,taking advantage of demand-side resources to reduce the abandonment of wind and light in micro-grid and to maximize the net present value(NPV)of micro-grid,a generalized energy storage scheme is proposed based on the upper layer.Finally,through the comparison of three different strategies,it is proved that when the demand side participates in the response,the win-win between the user and the grid can be achieved.
