考虑虚拟电厂可信容量的新能源电力系统容量市场出清模型
A capacity market clearing model for renewable energy power system considering unforced capacity of virtual power plant
摘要
Abstract
With the rapid growth of wind and photovoltaic power,the power system is facing issues of insufficient adequacy.To ensure an ample capacity supply,it is necessary to introduce the capacity market mechanism.Compared to the large-scale thermal power plants with long construction periods and high investment costs,virtual power plants(VPP)that aggregate distributed adjustable resources has a short-er construction period,lower investment,and quicker effectiveness.VPPs serve as effective resources for providing generation capacity to the system,they can be used to manage the peak demand.Therefore,a VPP unforced capacity(UCPA)formula and a comprehensive capac-ity market clearing model which is designed to consider capacity offers including VPP is proposed.The proposed VPP UCAP computation formulas consider power capacity,energy capacity and operational attributes.The proposed capacity market clearing model introduces the participation of VPPs with the consideration of wind power,photovoltaic power and conventional generation units.The presented capacity market clearing model considers system constraints such as peak demand,base demand,energy requirement,off-peak demand,and ramp power demand.Finally,the impact of UCPA of VPP,total capacity demand and renewable energy installed capacity on market cleared re-sults is analyzed by conducting the study cases,it shows the validity of the proposed VPP UCPA formulas and the capacity market clearing model.关键词
