Abstract: Today, the virtual power plant concept has received considerable attention by researchers. A virtual power plant is a set of distributed generations, controllable loads and energy storage systems that are managed in an integrated manner by a central control system. In this study, a new model for participating of a virtual power plant in the day-ahead electricity market is proposed. The aim of proposed planning is to maximize/minimize the virtual power plant’s profit/cost. In this regard, the uncertainties in loads as well as the generation of wind and solar energy units are modeled well. It has been assumed that the virtual power plant is connected to a microgrid in the downstream and to a high-voltage grid in the upstream. The proposed method is simulated on a standard IEEE 33-bus system for two strategies. In the first strategy, planning is performed without considering uncertainty of parameters. In the second strategy, model outputs are determined considering uncertainty in generation of the wind unit, generation of the solar unit and the load. Analysis and comparison of the results indicate the effectiveness of the proposed method.
