Voltage profile enhancement in distribution network using static synchronous compensator STATCOM

Abstract

STATCOM is one of FACTS devices that used as regulator for transmission and distribution systems which works for reactive power compensation. STATCOM utilisation in distribution system mostly for enhancing the profile of voltage, where used for adjusting the disturbance voltage by injecting into the system a controllable voltage. This paper present a Fuzzy controller based on STATCOM to enhance the voltage profile in distribution network. The controller of STATCOM has simulated for different types of abnormal load conditions of balance and unbalance load. The results of simulation show ability of proposed design to enhance the load voltage which was 96% of the nominal value.

Determining optimal location and size of capacitors in radial distribution networks using moth swarm algorithm

“…The process for calculating MSA method is implemented on a PC with processor Core i5 -2.2 GHz and 4GB of RAM. In addition, after determining location and size of capacitors, power flow method is applied to calculate branch currents and then power loss is obtained by using (1). Population size and the number of maximum iterationsare set to 30 and 100.…”

“…Also, distribution lines are developing large and being extended. A solution to the mentioned difficulties can be solved by installing distributed generators [1] or adding capacitors at proper locations [2]. In this paper, we only focus on finding the best location and the most appropriate size of capacitors in radial distribution networks.…”

Voltage stability enhancement for large scale squirrel cage induction generator based wind turbine using STATCOM

“…To achieve the previously mentioned system requirements, flexible AC transmission system devices FACTS such as STATCOM and UPFC are being used widely in control of power systems due to their ability to provide reactive power balance and flexible power flow control [22]. STATCOM has the ability to override voltage stability threats, this paper explores the impact of installing STATCOM at different voltage points to mitigate the adverse effect of some common contingencies on the operation and the stability of the distribution system connected to SCIG wind turbines, where system voltage profile and reactive power balance are compared for both healthy and contingency scenarios.…”

Real-time simulation of static synchronous condenser (STATCOM) for compensation of reactive power

“…In the general case, the main objective of the STATCOM control circuit is to correct the power factor under delayed/main loads with the absorption or injection of a current, which is the image of the reactive power of compensation [24,25]. These currents are the variables that determine the Statom references from the injected or absorbing powers.…”
