Optimal Reactive Power Dispatch (ORPD) is one of the main challenges in power system operations. ORPD a non-linear optimization task that aims to reduce active losses transmission grid, minimize voltage variations, and improve stability. This paper proposes an intelligent augmented social network search (ASNS) algorithm for meeting previous compared with (SNS) algorithm. The users’ dialogue, im...

One of the most crucial functions in the operation and control of power system is reactive power dispatch (RPD).A hybrid Big Bang–Big Crunch (HBB–BC) optimization algorithm which consists of A Big Bang– Big Crunch algorithm combined with particle swarm optimization (PSO) is proposed in this paper in order to solve optimal reactive power dispatch (ORPD) problem. The L-index of load buses is base...

Introduction: Optimal power flow (OPF) is an enhanced form of the economic dispatch (ED) optimisation problem where both active and reactive powers are treated as control variables and adjusted to minimise generation cost while observing associated power flow constraints. The constraints include but are not limited to thresholds on bus voltages, reactive power generation and the thermal ratings...

Reactive power plays an important role in supporting the real power transfers by maintaining voltage stability and system reliability. It is a critical element for a transmission operator to ensure the reliability of an electric system while minimizing the cost associated with it. The traditional objectives of reactive power dispatch are focused on the technical side of reactive support such as...

In this paper, new optimal power flow (OPF) techniques are proposed based on multi-objective methodologies to optimize active and reactive power dispatch while maximizing voltage security in power systems. The use of interior point methods together with goal programming and linearly combined objective functions as the basic optimization techniques is explained in detail. The effects of minimizi...
