VOLTAGE REGULATION WITH REACTIVE POWER CONTROL OF AN OPTIMIZED 30-BUS POWER SYSTEM

In recent years, energy, environment, right-of-way and cost problems and ‘quality need’ have delayed the construction of both generation facilities and new transmission lines. These problems have necessitated a change in the traditional concepts and practices of power systems. The objective of the work presented in this report is to make an EP based algorithm for solving the optimal power flow (OPF) problem without and with compensating device. The objective in the OPF problem formulation is the minimization of total cost of real power generation. Taking into consideration power balance equality constraints, limits on the control variables namely active power generations, controllable voltage magnitudes, limits on the dependent variables namely reactive power generations and load bus voltage magnitudes and limits on MVA line flows as the inequality constraints. Also, with the technique of series compensation, the quality i.e. voltage and reactive power loss is regulated.
