配网分时电价实用预测模型研究

在电力市场环境下,进行准确的电价预测对市场中的各参与者具有极其重要的意义.针对配网分时电价,本文使用规划优化方法,采用一般时段划分,集中负荷具体到配网变电站的每条出线,建立了优化的配网分时电价预测模型,并根据经济学原理定义电价.通过数学规划的Kuhn Tucker条件,求得电价的计算公式.探讨了电价公式中各分量的计算方法,并进一步通过算例初步验证了本模型的有效及实用性.

Study on the Time-Sharing Price Practical Forecasting Model in Distribution Networks

Accurate electricity price forecast is of great importance to the participants of power market.The paper proposes the optimal model of electricity pricing in distribution networks.The electricity price is defined according to economic theory.Utilizing mathematical analysis to pricing mode,the formula of pricing electricity is then presented,and the algorithms of calculating items in pricing formula are also discussed.In the end,a numerical case study is given to demonstrate the usefulness and rationality of the model suggested.
