考虑供需关系的新疆发电企业经济效益区间优化

Economic benefit interval optimization of Xinjiang’s power generation enterprise considering supply and demand relationship

为缓解各类型发电企业的利益冲突问题,构建基于电力市场交易的风光火电源经济效益均衡模型。考虑到新疆电网的复杂性且不同地区发电企业间的成本和收益具有较大差异,将火电分为北疆、南疆2个区域,风电和光伏按照资源区进行划分。将市场化交易电量占比设为区间数,在电力市场中考虑供需关系变化对电价的影响,并对3类电源的发电并网及交易策略进行分析。研究结果表明,通过3类电源参与市场交易,能够在保障三方利益的同时提升新能源的利用率。

In order to alleviate the interest conflict problem of various types of power generation enterprises,an economic benefit equilibrium model of wind-photovoltaic-thermal power sources is built based on electricity market transaction.Considering the complexity of Xinjiang Power Grid and great differences of costs and benefits among power generation enterprises in different regions,the thermal power is divided into two regions of northern and southern Xinjiang,and wind power and photovoltaic are divided according to the source areas.The proportion of market transaction electricity is set as an interval number,the influence of variation of supply and demand relationship on electricity price is considered in the electricity market,and the power generation grid-connection and transaction strategies of three types of power sources are analyzed.The research results show that the utilization rate of new energy is increased while the interests of three types of power sources are ensured by their participation in market transaction.
