Available transfer capability (ATC) based nodal pricing

Abstract

The transmission pricing depends on generator, load levels and transmission line constraints. The transmission system places an importance on the intensive use interconnected network reliably, which requires knowledge of the complex capability. Available Transfer Capability (ATC) is a compute of the remaining power transfer capability of the transmission network for further transactions. Available transfer capability in the transmission system has become essential quantity to be declared well in advance for its commercial use in a competitive electricity marketplace. The proposed approach of ATC using AC Power transfer distribution factors (AC PTDFs) based approach has been used for single and concurrent transactions using power transfer distribution factor and ATC based Locational Marginal Pricing methodology is used to decide the energy price for transacted power and to handle the network congestion and marginal losses. Simulation is carried out on IEEE30 bus system.
