Abstract--To meet the requirement from new visions within "smart grid" and to provide solutions for many challenges that DSOs (Distribution System Operators) are facing today, we need to develop advanced DMS (Distribution Management System) applications. A centralized Volt/Var Control (VVC) is one of the most desirable and important functions within Distribution Automation systems and DMSs.The overall Volt/Var control function is concerned with maintaining system voltage profile within a desired range and minimizing system losses by controlling the reactive power flow.The main objective of this paper is to review and evaluate the existing and recent techniques and algorithms for advanced VVC applications and identify the requirements for integrated Volt/Var control and optimization function in distribution management systems within the smart grid concepts.

“…The complexity of this problem differs significantly from placing only fixed banks because of the switching time of switched banks represents another variable to be determined. A solution to the volt/var problem in distribution system by decoupling the capacitor and regulator problems and combining them into a global solution determined analytically [5]. The real size of the feeder was considered by introducing the concept of "normalized equivalent feeder".…”

This paper presents hierarchical compensation technique for loss minimization in distribution system by optimum location of capacitor. The electric distribution system serves an important role in achieving satisfactory power supply. The power quality is measured by good voltage profile and voltage stability. In addition the distribution system should be operated under optimum loss condition. In view of recent power sector reforms lot of emphasis has been given to these aspects. In order to get optimized operating condition the reactive compensation methodology is adapted. The proposed approach identifies the proper location & size of compensation depending on the main feeder, laterals, and sub laterals owing to their hierarchy. The cost analysis gives the amount of saving achieved per annum. The approach is tested on 15 bus test distribution system. The technique serves as a useful tool for optimized distribution system operation.

“…The real-time control of voltages in the traditionally passive distribution systems (DSs) has been usually performed by the classical Volt/VAR control [1], [2]. The latter relies on local automatic discrete voltage controllers such as the on load tap changing (LTC) and shunt capacitors switching and aims at maintaining voltages on the DS between their statutory limits.…”

Abstract-This paper deals with the management of voltage constraints in active distribution systems that host a significant amount of distributed generation (DG) units. To this end we propose a centralized optimization approach which aims at minimizing the amount of MW curtailment of non-firm DG to remove voltage constraints. The salient feature of this approach is that it comprehensively and properly models the full variety of possible control means (i.e. DG active/reactive power including DG shut-down, on load tap changing transformer ratio, shunt capacitor, and remotely controlled switches or breakers), most of which having a discrete behavior. We develop and compare the performances of two optimization models on a snapshot basis for various distribution systems up to 1089 buses. In particular we show that the use of remotely controlled switches so as to transfer DG between feeders in case of voltage constraints may lead to significant reduction of the DG curtailment.
