基于关口点电价的购电成本分析

Analysis on Gateway-Price Based Power Purchase Cost

当前电网的经营正从精细化管理向精益化管理转变,但是相关人员缺乏有效工具来跟踪购电成本变化并进行相关分析,严重影响了电力交易的灵活性与时效性。为解决这一不足,及时动态获取当前时刻的购电单价,简化电价变化的相关因素分析,以满足电网公司的精益化管理需求,建立了一种关口点电价信息的购电成本与单价分析模型,并应用全微分方程分析了该模型的合理性与灵敏度,开发的关口信息管理平台应用,表明该模型可有效提升公司经营管理的可控、能控、在控能力,也证明了该模型的实用性。

Grid operating is transforming from meticulous management to lean management at present,however,it is the lack of an effective tool for tracking power purchase cost variation and correlation analysis that has seriously affected the flexibility and timeliness of electricity trading.To address this deficiency,timely and dynamic access to the current moment of electricity unit price analysis and simplify the electrovalence changes so that it will meet the demand for lean management of the grid,this paper proposed a model for power purchase price and cost analysis based on gateway electricity price information,and used the total differential characteristics to analyze the model＇s rationality and sensitivity.Through the trial of on the platform of power gateway metering information management for Liaoning power network has showed that the model can effectively enhance the controllability of the company＇ s management,controllability,the ability to control,thus also proving the usefulness of the model.
