This paper is about the dust effect impact on photovoltaic systems on the profit of an electricity market agent acting as an aggregator of photovoltaic power, wind power, thermal power, and an energy storage system. Energy storage ensures arbitrage and smoothing of the variability of photovoltaic power and wind power. The market agent intends to derive bids for submission in a day-ahead market, having consideration of the dust effect impact on the photovoltaic power. A formulation is proposed for a support decision system by a profit-based unit commitment problem solved by a stochastic programming approach, considering the operating characteristics of the virtual power plant. The photovoltaic power, wind power, and market price uncertainties are input data derived from scenarios of historical data. Case studies addressed show the advantages of the stochastic programming approach and insights concerned with the integration of uncertainties within the modeling for the schedule of the energy storage system and the dust effect impact on profit.

本文是关于灰尘效应对光伏系统的影响，该尘埃影响着充当光伏发电，风能，火力发电和储能系统聚集者的电力市场代理商的利润。储能确保光伏发电和风力发电的套利和平滑。考虑到粉尘效应对光伏发电的影响，市场代理商打算在日前市场中获得投标书。考虑到虚拟电厂的运行特性，提出了一种基于利润的单位承诺问题的支持决策系统的解决方案，该问题通过随机规划方法解决。光伏发电，风力发电和市场价格的不确定性是从历史数据场景中得出的输入数据。
