Joint operation of wind power and flexible load as virtual power plant

One of the main characteristics of wind power is its intermittence and unpredictability even in short time. To cope with this drawback, demand side participation has been proposed as a good complement to wind power due to its ability to manage positive and negative imbalances over time. This paper presents a mathematical model to derive the best offering strategy for virtual power plant (VPP) that aggregates wind power and flexible load in an electricity market. In this model the uncertainties of wind power are covered by flexible load in critical hours. Also, the flexible load as a storage unit can recover itself during off-peak hours. The suggested model is implemented on a real wind farm, and the results show its efficiency and validity.
