Optimal integration of wind power resources in distribution networks considering demand response programs

Distribution network operators (DNOs) tend to supply electrical energy to its customers in an economical and reliable manner. If wind power generation (WPG) units are planned with a suitable way, they will be the best option to reduce costs and increase the distribution network reliability. This paper proposes a WPG units planning model to determine technology type, capacity and location of WPG units to reduce power losses and improve reliability and voltage profile in network. In this model, DNO has been considered to study the effect of demand response programs (DRP) on total cost function, where the time-of-use rates of demand response programs have been modeled and consequently its influence on load profile has been discussed. Objective function is a cost function which minimizes the investment and operation cost of DGs, purchase costs of the upstream network, defined cost to reliability index and the energy losses. In this study, electrical load is time variable and model is simulated on a typical radial network, successfully.
