Application of power circle to reactive power optimization
2014 IEEE PES Asia-Pacific Power and Energy Engineering Conference (APPEEC), 2014Reactive power optimization has been a hard problem for years. However, the existed optimization algorithms are usually complex in calculation and not obvious in physical meaning. To study a simple and effective method for reactive power optimization, this paper puts forward a concept of optimal reactive load, and proposes a method called power circle ...

Constrained Optimal Reactive Power Procurement in Power System
2018 International Conference on Smart Electric Drives and Power System (ICSEDPS), 2018Modern power system operate under constrained settings due to insufficient generation and transmission capacities. Availability of reactive power in the system plays an important role in maintaining voltage stability. Secure and reliabme operation of the system greatly depends on adequate supply of reactive power.

Optimal reactive power control for industrial power networks
Conference Record of 1998 IEEE Industry Applications Conference. Thirty-Third IAS Annual Meeting (Cat. No.98CH36242), 1999In addition to process steam and real power demands, manufacturing processes also have a varying reactive power demand that must be satisfied. Reactive power affects line currents and bus voltages, as well as power factor of the tie-line bringing power into the industrial plant from the local utility. The local utility applies a penalty if the tie-line

Reactive Power Optimization in AC Power Systems
2017Reactive Power is one of the most important features in power networks so that its appropriate production and distribution among consumers can affect performance, efficiency, and reliability of the power networks positively. Creating competitive mechanism via establishing a market to present different services and changing the current rules necessitate

Network Optimization-Based Reactive Power Margin Calculation
IFAC Proceedings Volumes, 1988Abstract This paper proposes a method to compute the maximal reactive power load which can be consumed at a given set of buses, subject to a set of operating constraints, involving for instance generator reactive production and bus voltage limits. It can be used in particular to determine margins with respect to voltage collapse or, more generally ...

Particle Swarm Optimization Based Optimal Reactive Power Dispatch
2015 IEEE International Conference on Electrical, Computer and Communication Technologies (ICECCT), 2015Optimal reactive power dispatch is one of the major and important optimization problem in electrical power system operation and control. This is nothing but multi objectives, nonlinear, minimization problem of power system optimization. This paper focuses on this sub problem of optimal power flow.

Seeker Optimization Algorithm for Optimal Reactive Power Dispatch
IEEE Transactions on Power Systems, 2009Optimal reactive power dispatch problem in power systems has thrown a growing influence on secure and economical operation of power systems. However, this issue is well known as a nonlinear, multimodal and mixed-variable problem. In the last decades, computation intelligence-based techniques, such as genetic algorithms (GAs), differential evolution (DE)

OPTIMAL CONTROL OF VOLTAGE AND REACTIVE POWER OF POWER SYSTEM
IFAC Proceedings Volumes, 1987Abstract In this paper, from the view point of economy and security of a power system, a synthetic mathematical model is presented for minimizing system losses and improving voltage level. At the same time, it is taken into account that when the reactive power is insufficient or it is hard to operate the system normally, the system will be supplied ...

Optimal reactive compensation in power systems
Computers & Electrical Engineering, 1982Abstract This article describes a method for planning the type, location and minimum amount of installed reactive capacity necessary for maintaining an acceptable voltage profile in a power system during credible contingencies. The problem is formulated as the minimisation of the cost function representing the total cost of the reactive compensation ...
