Economic load dispatch with ATC improvement in power system network including solar power generation systems

摘要

The present work deals with the active power rescheduling in an hour-ahead electricity market including solar energy based power generation. The schedules of various generators have been optimized according to active power demand bids by various load buses and availability of solar energy. In this work, various aspects such as congestion management, voltage deviation, and loss minimization have also been taken into consideration to achieve the goal. The interior point (IP) based optimal power flow (OPF) methodology has been used to obtain the economic system operation. The IP-based OPF methodology has been tested on a modified IEEE-30 bus system. The obtained test results show that not only the generation cost is reduced also the available transfer capabilities of transmission lines have also been improved.
