摘要
随着现货市场建设的不断推进,跨省区水电如何参与现货市场的机制和相应策略越来越受到业界的关注。针对跨省区水电具有独特的特性与成本模式,在中长期合约交割方面,针对跨省区水电功能性约束多、体量大、多省消纳等特点,设计了中长期合约分解曲线物理执行的机制;在日前市场方面,由于水电的成本与其耗水量对应的机会成本直接相关,设计了基于电量量价曲线的日前市场增量竞争机制。在水电交易策略方面,提出了基于水价值的跨省区水电中长期合约分解曲线制定策略和模型,使得当期的中长期合约交割充分计及未来的预期收益;针对水电缺乏边际成本参考这一难题,构建了跨省区水电日前市场增量报价决策模型,通过测算边际水价值曲线,为水电日前市场报价提供了科学决策的依据。
With the development of spot market construction,the mechanism and strategy of trans-provincial hydropower participating in the spot market have attracted more and more attention in the industry.Trans-provincial hydropower has its unique characteristics and cost model.In terms of its delivery in the medium and long-term contracts,a physical execution mechanism of the decomposition curve in the medium and long-term contracts is designed in view of the features of multi-functional constraints,large volume and multi provincial consumption of trans-provincial hydropower.In terms of the day ahead market,the cost of hydropower is directly related to the opportunity cost corresponding to the water consumption volume rather than to the power.An energy-based incremental bidding mechanism of the day ahead market is designed.In the aspect of trans-provincial hydropower trading strategy,the strategy and model of the medium and long-term contract decomposition method based on water value is proposed in this paper,so that the future expected benefits will be fully taken into account in the delivery of the medium and long-term contracts.In order to solve the problem of lack of marginal cost reference of hydropower,a decision-making model for the incremental bidding of the day ahead is constructed.The marginal water value curve is calculated as the reference for the day ahead market bidding of trans-provincial hydropower.
