Usage based Power flow for Transmission Line Cost Estimation in Bilateral Power Market using Power Flow Tracing Principle

transport electrification
The deregulation of electric power sector produces various issues in supplying the power to the transmission lines and loads. The transmission cost in the restructured power market exhibits several impacts on the transmission pricing. The loss in the transmission lines occur either due to power contributed by the generator or by the power shared by the load. Therefore, the transmission pricing calculations depend on both generator and load power flow. Many transmission pricing schemes are adopted to determine the transmission cost. This paper introduces a new method to calculate the transmission cost using usage based power flow. The power usage in the transmission lines is determined with the help of power flow tracing principle. The power flow tracing is achieved by maximizing the real power flow in generator bus. The optimization of real power is done by applying Particle Swarm Optimization (PSO) algorithm. This method of pricing is tested on IEEE 30 bus system and Indian Utility-69 bus system under bilateral power market.
