Abstract

This paper proposes a new approach to examine the voltage security of the system. An approximate linear model that comprehensively includes the line flows and bus voltages in its formulation is the basis for analysis. Linear programming (LP) approach is used to calculate the load scenarios, which ensures the system security. Forecast of load scenarios that lead to system security is also possible. The linear programming is implemented using Excel spreadsheet [Microsoft EXCEL 2002]. The new methodology is implemented on a 5 bus system and the voltage profile is assessed. The results are verified by a power flow algorithm [ETAP Power Station 3.0]. The methodology is also implemented on the 14-bus IEEE system.
