Abstract

The important implication of complex-variable Newton-Raphson load flow analysis is that reduction in memory access is achieved by the complex-variable Newton- Raphson method. This significant reduction in memory access achieved will lead to the advantage of substantial reduction in computing time which will increase the efficiency. In addition complex-variables offer a flexible and direct approach for modelling of UPFC. This paper develops a Newton-Raphson load flow analysis formulation which includes UPFC. A brief analysis on load flow calculation methods and UPFC is presented. Proposed system is simulated for IEEE 30 BUS system using Mi-Power software.

Keywords
