Abstract
The transmission network plays an important role in deregulated electricity markets because it is the key mechanism for generators to compete in supplying large users and distribution companies. Congestion in transmission network could be one of the primary problems of restructured electric industry. This paper proposes a new method to enhance the line loadability by congestion management using power vector graph method. In some methods like sensitivity analysis, only active power is taken to do congestion management so those methods are not accurate. But here, both active power and reactive power are considered for doing congestion management. The active and reactive power flow of individual sources in the network and contribution of each source to each line is evaluated by the use of superposition principle. Power vector graph is designed with the help of the power flows in the context of a competitive electricity market. Congestion can be reduced to enhance line loadability by adjusting relevant power components in four quadrants. Proposed method is illustrated on IEEE 30 bus system using MATLAB.
