In the practical power system, power plants are not at the same distance from the centre of load and their fuel costs are also different. Generally the power generation capacity is more than the total load demand and losses under normal operating conditions. Thus there is a need to find an effective real and reactive power scheduling to power plants to meet load demand as well as to minimize th...

Flexible AC transmission system; Static synchronous compensator (STATCOM); Optimal reactive power dispatch (ORPD); Chemical reaction optimization (CRO); Transmission loss Abstract Optimal reactive power dispatch (ORPD) problem has a significant influence on optimal operation of power systems. However, getting optimal solution of ORPD problem is a strenuous task for the researchers. The inclusio...

This paper presents a new framework for the day-ahead reactive power market based on the uniform auction price. Voltage stability and security have been considered in the proposed framework. Total Payment Function (TPF) is suggested as the objective function of the Optimal Power Flow (OPF) used to clear the reactive power market. Overload, voltage drop and voltage stability margin (VSM) are inc...

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...
