In times of increasing industrialization and domestic utility requiring electricity, deregulated power or electricity concepts have been gaining widespread significance in recent times. Deregulated power signifies and reflects power transmission sectors/companies defining their own set of rules and regulations in an attempt to get relieved from a centralized control pattern, consequently leading to the improvisation of efficiency. However, deregulated power system experiences power instability issues at times of varying demands at the load side, which may be attributed to several reasons. Under such circumstances, power congestion along the transmission lines is observed, which is quite challenging. These further causes stress on the management of the deregulated power system concerning power distribution in the current competitive environment amongst various other transmission stakeholders. It has been taken as the problem formulation in this paper, and a Local Marginal Pricing (LMP) mechanism using a Linear Programming (LP) methodology has been proposed in this work. DC optimal power flow (DCOPF) concept has been taken as the base platform for the proposed LMP formulation. LMP is effectively used for assessing the pricing scheme of the different buses, while DCOPF aids in reducing the congestion effect due to varying peak loads. IEEE 5 and 14 bus system has been used in the proposed power flow analysis and pricing scheme. Superior performance is observed in the experimentation, justifying the validity of LP.
