In practical situations, distribution network loads are the mixtures of residential, industrial, and commercial types. This paper presents a hybrid optimization algorithm for the optimal placement of shunt capacitor banks in radial distribution networks in the presence of different voltage-dependent load models. The algorithm is based on the combination of Genetic Algorithm (GA) and Binary Part...

The lack of reactive energy flow control in distribution networks causes an increase of electrical losses and problems with the voltage profile. The main objective of this work is to develop a fuzzy control system for automatic capacitor banks applied to distribution feeders, which was focused on the improvement of the equipment performance allowing a better correction of the system reactive an...

Various inductive loads used in all industries deals with the problem of power factor improvement. Capacitor bank connected in shunt helps in maintaining the power factor closer to unity. They improve the electrical supply quality and increase the efficiency of the system. Also the line losses are also reduced. Shunt capacitor banks are less costly and can be installed anywhere. This paper deal...

This paper proposes an automatic discrete slow voltage controller, which is motivated towards implementation in the western Oregon system in Pacific Northwest. This part of the system is far from generators and the main voltage control devices are capacitor banks, reactor banks and LTC transformers. The project pursues a model-based approach for selecting the discrete control actions for on-lin...

In larges electrical system used in industries, office builidings, or hotels, capacitor banks are usually utilized to compensate the required VAR absorbed by the loads. As the nonliniear loads are increasing rapidly, the risk of resonance phenomenon occured is becoming higher as its terminal voltages are not anymore sinusoidal. On the other hand, many customers have become aware to the problems...

The widespread integration of photovoltaic (PV) units may result in a number of operational issues for the utility distribution system. The advances in smart-grid technologies with better communication and control capabilities may help to mitigate these challenges. The objective of this paper is to evaluate multiple voltage control methods and compare their effectiveness in mitigating the impac...

Topology for reactive power compensation of dynamic load in closed loop is presented. The scheme consists of Thyristor Binary Switched Capacitor (TBSC) banks and a Thyristor Controlled Reactor (TCR). TBSC is based on a chain of Thyristor Switched Capacitor (TSC) banks arranged in binary sequential manner. TCR capacity is chosen to be smallest of TBSC step size. A transient free switching of TBS...
