Dispatch of reactive power compensators in transmission grids
Electric Power Systems Research, 2020 Abstract The phase-out of conventional power plants reduces the reactive power reserve from synchronous generators in transmission grids. Operational concepts need to be adapted to integrate reactive power compensators such as STATCOMs into voltage control schemes.

Comprehensive learning particle swarm optimization for reactive power dispatch
Applied Soft Computing Journal, 2010Reactive power dispatch (RPD) is an optimization problem that reduces grid congestion by minimizing the active power losses for a fixed economic power dispatch. RPD reduces power system losses by adjusting the reactive power control variables such as generator voltages, transformer tap-settings and other sources of reactive power such as capacitor ...

Optimal Reactive Power Dispatch Using SunFlower Algorithm
2021 International Conference on System Science and Engineering (ICSSE), 2021Optimal reactive power dispatch (ORPD) is one of the complicated problems in the power system operation since it optimizes a chosen objective while all power system constraints must be satisfied. Recently, many algorithms have been developed to solve the ORPD problem. This paper is applied a Sun Flower optimization (SFO) algorithm to solve ORPD problem

A Reactive Power Model for a Simultaneous Real and Reactive Power Dispatch
2007 IEEE Power Engineering Society General Meeting, 2007This paper investigates the simultaneous dispatch of real power and reactive power in restructured electricity markets. In this proposed method the opportunity cost of supplying reactive power is implicitly modeled using the rating of the machine as a constraint.

Collaborative optimization of economic dispatch and reactive power dispatch
2019 Chinese Control Conference (CCC), 2019Economic dispatch and reactive power dispatch are two important tasks in power systems, which respectively concern the economy and environmental friendliness and the safety and reliability of grid operation. Essentially different from the related literature with separately solving the two dispatches, this paper is devoted to collaboratively optimizing ...

Reactive-power dispatch by successive quadratic programming
IEEE Transactions on Energy Conversion, 1989The reactive-power dispatch is formulated as the minimization of real-power losses in the system, utilizing a full set of control variables: generator voltages, switchable shunt susceptances, and transformer taps. The solution of the loss problem is obtained by successively solving quadratic programming problems.
