Market oriented reactive power expansion planning
2008 5th International Conference on the European Electricity Market, 2008This paper presents a method for market oriented reactive power expansion. In this method first ISO proposes some locations for reactive power expansion based on system requirements and operatorpsilas experiences. The investors determine the optimal locations for reactive power expansion by computing annual expansion profit of different candidates ...

Reactive Power Planning using Evolutionary Algorithms
2010 INTERNATIONAL CONFERENCE ON COMMUNICATION CONTROL AND COMPUTING TECHNOLOGIES, 2010This paper proposes an application of Evolutionary Algorithms (EAs) such as Differential Evolution (DE), Evolutionary Programming (EP), Real coded Genetic Algorithm (RGA), Covariance Matrix Adaptation Evolution Strategy (CMAES) and Particle Swarm Optimization (PSO) to Reactive Power Planning (RPP) problem.

New tool for reactive power planning
IEE Proceedings C Generation, Transmission and Distribution, 1993A new tool for planning reactive power compensation is presented. It is based on the capability chart of the power system, which describes the domain of allowable operation of the system in the plane of total and reactive load demand. Reliability concepts are used to describe the ability of the power system to face the load; the stochastic approach is ...

Reactive power planning incorporating system security
Proceedings of 8th Mediterranean Electrotechnical Conference on Industrial Applications in Power Systems, Computer Science and Telecommunications (MELECON 96), 2002The purpose of reactive power planning is to provide an acceptable voltage profile and to maintain generators' reactive limits. A method is developed using a security performance index and an optimization technique. The proposed combined technique finds an optimal solution for a practical size power system by reducing the set of equations to be solved.

Over the years, voltage performance of a power system has received attention from both analysis and improvement points of view. Although voltage magnitudes are, normally, of main concern, during the last, perhaps, two decades, voltage stability is also received attention in literature. In this section, we try to briefly, differentiate between these two

Coordinated reactive power planning against power system voltage instability
2009 IEEE/PES Power Systems Conference and Exposition, 2009This paper implements a long term VAR planning algorithm developed earlier, which coordinates between network investments that most effectively address steady-state voltage instability and those which most effectively address transient voltage dip problems under severe contingencies.

Reactive Power Planning using Swarm Evolutionary Techniques
2020 2nd International Conference on Advances in Computing, Communication Control and Networking (ICACCCN), 2020Reactive power planning is known to be challenging issues for optimization. It refers to the adequate size and position of reactive power resources for regular working conditions as well as in the anticipation of a power system vulnerability or interruption.

Optimal reactive power planning using risk analysis
2013 IEEE Power & Energy Society General Meeting, 2013In this paper, the optimal reactive power planning problem under risk is presented. The classical mixed-integer nonlinear model for reactive power planning is expanded into two stage stochastic model considering risk. This new model considers uncertainty on the demand load.

A heuristic method for reactive power planning
IEEE Transactions on Power Systems, 1996An approach for solving power system reactive power planning problems is presented, which is based on binary search techniques and the use of a special heuristic to obtain a discrete solution. Two versions were developed, one to run on conventional (sequential) computers and the other to run on a distributed memory (hypercube) machine.

Evolutionary programming approach to reactive power planning
IEE Proceedings - Generation, Transmission and Distribution, 1996The paper proposes an application of evolutionary programming (EP) to reactive power planning (RPP). RPP is a nonsmooth and nondifferentiable optimisation problem for a multiobjective function. Several techniques to make EP practicable have been developed. The proposed approach is demonstrated with the IEEE 30-bus system.
