4. Conclusion
Renewable energy sources have attracted a lot of attention due to their cleanliness and stability. Recently, a significant number of redistributed distributed products (DGs) have intermittent production patterns that are connected to the distribution network to meet the growing needs of the freight demand, making environmental threats ineffective. Integrating the integration of renewable DGs into distribution networks is essential to ensure the quality and factor benefits of the network. In this paper, a simple and effective method for sizing, optimizing the placement of wind and solar DGs in distribution locations is presented, which also minimizes the loss of network power, improves voltage stability and network security. Accidental sunlight and wind speeds were also considered using possible appropriate models. Weighted particle optimization technique with weight accumulation has also been used to optimize target functions in which the bus voltage limit, line loading capacity, discrete size limit and DG penetration limits are considered.
