Abstract With the growing influence of fog and haze F-H weather and the rapid development of distributed energy resources DERs and smart grids, the concept of the virtual power plant VPP employed in this study would help to solve the dispatch problem caused by multiple DERs connected to the power grid. The effects of F-H weather on photovoltaic output forecast, load forecast and power system dispatch are discussed according to real case data. The wavelet neural network WNN model was employed to predict photovoltaic output and load, considering F-H weather, based on the idea of -similar days of F-H-. The multi-objective optimal dispatch model of a power system adopted in this paper contains several VPPs and conventional power plants, under F-H weather, and the mixed integer linear programming MILP and the Yalmip toolbox of MATLAB were adopted to solve the dispatch model. The analysis of the results from a case study proves the validity and feasibility of the model and the algorithms. View Full-Text
