With the rapid growth of renewable energy (REs) resources in the electricity sector, the system operators (SOs) are facing some major challenges related to security, market, and operations in power transmission. Since the government policies are providing subsidized and favorable terms; therefore, the investors are highly keen on the installation of REs in the power networks. Altogether, the REs wouldn’t be available 24 hours. Hence, the modern and upcoming power markets need to exchange power between different networks or regions (inter-regional) to meet the growing demands. The higher penetration of REs could cause overgeneration into the system due to low demands on the power systems, especially during mid-days. Therefore, inter-regional or inter-power markets strategies are the need in the present power systems to address the market clearing problems during the mentioned situation. In the present work, the locational marginal pricing (LMP) based solution methodology has been proposed to resolve the problem of market clearing in the power system during overgeneration. The objective function for the identified problem has been formulated using optimal power flow technique and solved through Interior Point Method (IPM). The interconnection of IEEE-9 & IEEE-5 bus systems and IEEE-118 & IEEE-57 bus systems have been chosen to create the inter-regional marketplaces. The proposed LMP based solution methodology has been implemented on these marketplaces. The obtained test results show that the proposed methodology provides an economic and efficient solution for the highly PV penetrated power system.
