Abstract
In this paper, an optimal reactive power dispatch problem is solved with an aim to maximize the Reactive Power Reserve (RPR) of power systems. The RPR of a system is the additional Reactive Power (RP) that can be supplied by reactive power sources over and above their current RP generations. The voltage stability indicator is critically dependent on RPR and in fact, the RPR is the capability of the RP sources to boost the bus voltages during power system operation. The problem is formulated as a nonlinear, non-convex optimization problem with continuous control variables. A recently developed meta-heuristic algorithm called ‘Salp Swarm Algorithm (SSA)’ is utilized to solve the problem. The problem is programmed in MATLAB and experimented on the standard IEEE 30-bus system. Various case studies are carried out to authenticate the effectiveness of SSA algorithm over other contemporary methods. Moreover, the effect of practical nonlinear loads on the variations of RPR is also investigated in this paper. Parametric sensitivity analysis of SSA is performed for each case to declare optimal results.
