摘要
传统厂级煤电机组负荷优化分配以确定的电量和电价水平为基础进行研究,而在电力现货场景下,电量和电价都是不确定且波动的,因此相比传统模式下的厂级煤电机组负荷优化分配问题更加复杂和具有挑战性.基于对市场供需形势的判断,考虑煤耗、爬坡速率、出力上下限、非经济运行区间等生产条件约束,以发电利润最大化为目标,利用二次混合整数规划算法确定最优的负荷分配方案,支持煤电企业以此为目标进行电力现货市场的报量报价决策.结果表明:负荷优化分配可以有效提升煤电机组利润,并且多日联合优化比单日优化能获得更大的发电利润,对于煤电企业优化运行方式、提升交易决策水平、提高效益水平具有重要意义.
Abstract
Studies on optimal load allocation of traditional plant-level coal-fired power units are based on fixed quantity of electricity and price levels.However,in the context of electricity spot markets,both electrici-ty quantity and price are uncertain and volatile,making the problem of optimal load allocation for plant-level coal-fired power units more complex and challenging compared to the traditional mode.Based on the market supply and demand trend judgment,and considering production constraints such as coal consumption,ramp rates,upper and lower output limits,and non-economic operation ranges,taking maximizing generation profits as the goal,a mixed-integer quadratic programming algorithm,is used to determine an optimal load alloca-tion scheme to support coal-fired power enterprises in making quantity and price decisions in the electricity spot market with this goal in mind.The results indicate that optimized load allocation can effectively increase the profits of coal-fired power units,and that multi-day joint optimization can yield greater generation profits than single-day optimization.This has significant implications for coal-fired power enterprises in optimizing their operational modes,enhancing their trading decision-making capabilities,and improving their profitability levels.
