Abstract :
Voltage security of modern power system remains an important aspect of sustaining our economies and high standards of living. The operation of such systems requires adhering to regulations to ensure that the system voltages throughout the network are kept within safe, contractual limits. Several researchers have investigated ways to determine voltage security that is affected by heavy loading conditions, switching of large loads, line switching, and/or unpredictable use of power from customers. These may result in local voltage swings, affecting the control systems. In this paper, we implement a control option, namely distributed generation (DG), with the added value of improving voltage deviation and the resulting energy transactions for the system operator. The implementation approach features the use of a value-based index that incorporates the use of locational marginal prices and the price differential at each node, with or without DG. The scheme was tested on a small-scale 30-bus benchmarked system.
