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

Optimal Reactive Power Dispatch Optimization Using STATCOM
Journal of The Institution of Engineers (India): Series B, 2021Optimal Reactive Power Dispatch (ORPD) is an advanced function which determines the best possible set of control variables (optimal solutions). Power system operates optimally on these optimal solutions. The objective of the ORPD is to minimize the transmission line losses and improves the voltage profile of the power system.

Optimal reactive power dispatch with fuzzy variables
1993 IEEE International Symposium on Circuits and Systems, 2002The authors present a consistent treatment of the optimal reactive power dispatch problem taking into account the uncertainty associated with load values. Linguistic declarations of loads are translated into possibility distribution functions via fuzzy sets.

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 ...

Optimal real and reactive power dispatch
Electric Power Systems Research, 1984Abstract This paper presents a method for optimal real and reactive power dispatch for the economic operation of power systems. As in other methods, the problem is decomposed into a P-optimization module and a Q-optimization module, but in this method both modules use the same generation cost objective function.

Genetic algorithm for optimal reactive power dispatch
Proceedings of EMPD '98. 1998 International Conference on Energy Management and Power Delivery (Cat. No.98EX137), 2002Scheduling of reactive power in an optimum manner reduces circulating VAr promoting flatter voltage profile which lead to appreciable MW saving on account of reduced power system losses. Hence, the optimal reactive power dispatch assumes extremely important functioning both in the planning stage as well as in day to day operation of the power system ...

Chance Constrained Optimal Reactive Power Dispatch
2018 IEEE Power & Energy Society General Meeting (PESGM), 2018The uncertainties from deepening penetration of renewable energy resources have already shown to impact not only the market operations, but also the physical operations in large power systems. It is demonstrated that deterministic modeling of wind would lead to voltage insecurity in the reality where wind fluctuates.

Security constrained optimal reactive power dispatch
Electric Power Systems Research, 1989Abstract This paper presents a systematic methodology to allocate reactive power devices in a power system. This is achieved through the application of an active set analysis based linear programming technique. The procedure takes into consideration outages which cause voltage problems and also existing reactive power controllers are fully utilized ...

A novel algorithm for the Optimal Reactive Power Dispatch
2018 20th National Power Systems Conference (NPSC), 2018The problem of Optimal reactive Power Dispatch (ORPD) is a non-linear and complex optimization problem having non-linear functions with many non-linear as well as discontinuous constraints. The solution of the problem helps in minimizing the active power losses, reduction of voltage deviation, improvement of the voltage stability margin, and thus ...
