ABSTRACT: Nowadays electricity
market industry is become a major impact on power system for privatization and
deregulation of power in global wise. As per the limitation of the transmission
system, the complexity arises and the supply fact will be with demand at the
time of balancing. The congestion of the power system is occurring based on the
transmission limits of the power desire and amount for operating the system. In
order to avoid transmission line congestion, enhanced STF-LODF method is
proposed. It shows the regulated line transmission flow with generating units
by implementing renewable energy resources (RER) based on enhanced STF-LODF in
power systems. It avoids the congestion of transmission line frequently in the
power system and manages price based on pricing and sensitivity approach, and
also manages optimal location of congestion transmission and instability issues
of voltage. The congestion management of Locational Marginal Pricing (LMP) is
performed with minimum line loss, less cost, line flow, better sensitivity and
better performances in optimal power flow and control flow. The efficiency of
the proposed power system is analyzed and verified by the simulation results of
tested IEEE 14 bus system.
