Raphson Method

Load Flow Analysis helps in error free operation of power system and also useful in forecasting the required equipment for expansion of the system. By forecasting the magnitude of the supply required along with effects caused by single or multiple defects in the system and calculating the magnitude of errors, it is very easy to compensate them using various techniques with minimum cost and effort. It means before installation the favorable sites and size of the infrastructure used are determined to maintain the power factor in the system. Here Power Flow Analysis is performed using Newton Raphson method. This method is used in solving power flow studies of various number of busesunder various conditions. In any network there will be undesired rise or drop or dissipation of voltage. Voltage instability decreases the efficiency of the system and also damages the equipment used. Hence voltage instability analysis is performed and magnitude of the instability is calculated and compensated using various techniques. Here we performed Load Flow Analysis on a 5bus system and Voltage Instability Analysis is also performed to the same with necessary outputs.[7]

The paper describes the development and features of an MS-Excel Workbook (available at www.reseeds.com ), which illustrates four methods of power system load flow analysis. Iterative techniques are represented by the Newton-Raphson and Gauss-Seidel methods. The Workbook also includes two search algorithms: genetic algorithms and simulated annealing.

Voltage Stability Enhancement

With the ever increasing demand of power, the major concern that has aroused is the problem of voltage instability. Due to voltage instability several major power system failures and blackouts occur. Voltage stability thus becomes a necessity. For this FACTS devices like SVC, STATCOM, etc. are used. Load Flow analysis and Continuation Power Flow Analysis is done to identify the weak buses and FACTS devices are installed in these weak buses to enhance the voltage stability. This paper presents a network formulation of IEEE 30 Bus test system using MATLAB and PSAT software and then comparing the effect of SVC and STATCOM for voltage stability enhancement.
