Abstract EN
In restructured electricity markets, an effective transmission pricing method is required to address transmission issues and to generate correct economic signals.
Transmission line constraints can result in variations in energy prices throughout the network.
These prices depend on generator bids, load levels and transmission network limitations.
A congestion charge is incurred when the system is constrained by physical limits.
Locational marginal pricing (LMP) has become popular method in restructured power markets to address the congestion price.
This paper presents, Genetic Algorithm (GA) based DCOPF model to calculate LMP’s at all buses considering concentrated loss model and a distributed loss model to remove the high mismatch at the slack bus.
LMP decomposition is also given, which can be decomposed into energy price, congestion price and loss price.
The developed models have been applied for IEEE 14 bus, New England 39 bus system and 75 bus Indian Power System.
Comparison is made between Linear Programming (LP) based DCOPF using Power World Simulator and the developed GA based DCOPF for concentrated and distributed loss cases.
Both fixed and linear bids are considered for generators.
The load is assumed to be inelastic.
Distributed loss model considering linear bids shows reduced generation fuel cost compared to concentrated loss model.
