摘要 考虑需求侧对电力市场交易的影响,提出了一种考虑环保和需求响应的多目标中短期交易计划修正模型。采用修正β参数的灰色模型分口径预测需求侧月峰、平、谷电量,结合考虑购电费用、环保和网损最小确定计划发电量。当电价变化后,利用电量电价弹性矩阵(E矩阵)计算出新的决策月峰、平、谷口径电量,得出考虑需求相应的修正月交易计划。提出奖惩费用,使得当修正电量波动到某一程度时购电价格随之变动,从而通过影响全网购电费用进一步影响交易计划。所提模型对交易中心具有辅助决策意义。 Considering the effects on electricity market demand side,a revised model for medium and short-term trade planning is presented.It firstly forecasts the industry electric quantity of peak,flat,valley monthly on the demand side using the parameter-modified grey model and considers the minimum of power purchase cost,environmental protection and the network loss to determine the generation scheduling.With the fluctuation of electricity price,the price elasticity matrix computes the new industry electric quantity of peak,flat,valley monthly and gets the revision trade planning of the month.Then it gives the penalty cost,when the correction value reaches a certain level the electricity price will change with it,thus influences the trade planning by impact on the all-network power purchase cost.The model proposed can be used as an auxiliary decision-making for the trading center.
