This paper presents a comprehensive survey on application of various conventional, optimization and artificial intelligence (AI) based computational techniques for impact assessment of optimally placed and coordinated control of distributed generations (DGs) and flexible AC transmission systems (FACTS) controllers in power systems (PSs). This review work is presented from the viewpoint of different performance criterion enhancement of PSs such as minimization of active and reactive power losses and reduction of cost of system, more flexible operation and control, increase overall system energy efficiency, increase reliability of system, relieved transmission and distribution congestion, enhance power quality (PQ) of system, improve the voltage profile (VP), increase the loadability of systems, increase available power transfer capacity (APTC) of system, enhance PS stability, reduce PS oscillations, improve environmental GHG conditions and provide the reactive power support in emergency case such as under fault, sudden change in field excitation of alternators or load increase in PSs. This paper also presents the current status of the various conventional, optimization, and AI computational techniques for optimally placed and coordinated control of DG and FACTS controllers in PSs for enhancement of PSs performance parameters. Authors strongly believe that this survey will be very much useful to the researchers, scientific engineers, industrial persons working in this area to find out the relevant references and current state of the art.

A survey on impact assessment of DG and FACTS controllers in power systems

A methodology called the sensitivity tree, which can be easily used to form an expert system for real-time control, is proposed. Based on this methodology, an expert system for the control of voltage and reactive power of a power system is developed. The main objective of this expert system is to help the operator detect buses experiencing abnormal conditions, select the most effective control measures, and calculate the control actions required to overcome the voltage violation. The control measures used to alleviate the voltage problem are capacitor compensation, transformer tap changes, and generator terminal voltage changes. By keeping the bus voltage in the entire system within limits, system security is increased. The expert system is written in the PROLOG language. Simulation studies with this expert system applied to a 30-bus power system show satisfactory results. >

An expert system for voltage and reactive power control of a power system

A two-level decomposition technique for VAr (voltampere reactive) sources planning in electric power systems is presented. Several operating conditions of the system (different base cases with associated contingencies) can be considered simultaneously. Total flexibility in the corrective or preventive treatment for control variables is provided. New VAr sources are modeled by discrete variables, and the operating and investment costs are discussed in detail. Examples of applications to actual cases of reactive compensation planning in a large power system are reported to demonstrate the efficiency and capabilities of the approach. >

A security-constrained decomposition approach to optimal reactive power planning

A method of solving the preventive security-constrained reactive power VAr dispatch problem is presented. A decomposition-coordination scheme is conceived in order to take advantage of the special structure of the problem. Instead of tearing the network, the problem itself is decomposed into smaller subproblems. Techniques are presented for contingency simulation and for the handling of these contingencies in the optimization process. The computing procedure is given for the step-by-step solution for online implementation. VAr-oriented load flow and optimal power flow methods are described. Numerical testing results are reported. >

Security-constrained reactive power dispatch

This paper presents development of an innovative tool for online power system operation. It is designed to operate in an energy control center (ECC) environment. Online application consists of using the developed optimal power flow (OPF) based loss minimization (LM) function for real time power system corrective actions by ECC dispatchers. The results of online power system operations using the LM function are reported to demonstrate economic and security gains for power system operations. >
