The incorporation of renewable energy sources into the power grid is pivotal in advancing a sustainable future. According to recent studies, Distributed generation resources can significantly reduce congestion in power networks. However, if these distributed resources are not planned smartly, they can sometimes aid in congestion and losses in the system. To address this issue, this paper employs a sequential approach to identify the optimal locations and sizes of distributed resources to mitigate congestion. This paper utilizes DC Optimal Power Flow (DC-OPF) methodology to compute Locational Marginal Pricing (LMP). Subsequently, Locational Marginal Prices (LMPs) are employed to ascertain the optimal location and size of the distributed source. The scheme is applied on three bus systems on two different simulation platforms, i.e. on the power world simulator and ETAP.
