摘要
As the share of renewable generations(RGs)in power systems grows,the demand for peak regulation has increased,leading to higher associated costs.In this paper,we propose a mechanism for allocating peak regulation cost among RGs and distributing compensation among peak regulation resources(PRRs).This mechanism is integrated into a coordinated generation scheduling model to enhance the economic efficiency of independent system operators(ISOs)and incentivize PRRs.First,we propose a model for peak regulation cost of diverse PRRs.Next,we develop a method for constructing an RG output curve that facilitates peak regulation.The waveform difference between this constructed curve and the RG forecasted output curve is then calculated.In addition,we create a mechanism for peak regulation cost allocation and compensation distribution that incorporates the waveform difference,the peak regulation contribution of PRRs,and participant satisfaction as key indicators.We then establish a coordinated generation scheduling model using this mechanism,which is solved through the column-and-cut generation algorithm and rolling optimization.Finally,we conduct case studies based on an improved IEEE 30-bus test system and perform several comparative analyses to validate the effectiveness of the proposed mechanism and coordinated generation scheduling model.
