Sources of energy for conventional power generation are limited and depleting ceaselessly owing to rising demand of power because of the social modernization, rising industrial growth, quick rate of infrastructure development and also technological innovation. Several developed countries have started the employment of renewable energy sources considerably to attenuate the greenhouse gases effects within the atmosphere and harmful emission. The rising demand of the power without any harmful and damaging issue, forces the eye of researchers towards renewable sources (like wind and solar) of energy. Therefore, it's minimum impact on the atmosphere. Renewable Energy sources are becoming the key contributors in the present society due to the increasing cost of oil products and decrease in the price of RES. By using natural resources energy sources like Solar and wind are providing green energy. Renewable Energy penetration is increasing worldwide day by day. Renewable power generation will introduce noticeable power quality challenges when integrated to power grid. From the aspect of RES, renewable energy generation is intermittent and non-dispatchable because of varied nature of RES. The most common PQ challenges on RE integration are frequency and voltage fluctuations in the power system caused by noncontrollable atmospheric condition and Harmonics that are introduced because of power electronic converters used in RE power generation. This paper presents an intensive literature review, conducted on emerging PQ issues owing to Solar and Wind energy systems integration and existing mitigation methods.

This paper furnish the new Metaheuristic algorithm called Cuckoo Search Algorithm (CSA) for solving optimal power flow (OPF) problem with minimization of real power generation cost. The CSA is found to be the most efficient algorithm for solving single objective optimal power flow problems. The CSA performance is tested on IEEE 57 bus test system with real power generation cost minimization as objective function. Static VAR Compensator (SVC) is one of the best shunt connected device in the Flexible Alternating Current Transmission System (FACTS) family. It has capable of controlling the voltage magnitudes of buses by injecting the reactive power to system. In this paper SVC is integrated in CSA based Optimal Power Flow to optimize the real power generation cost. SVC is used to improve the voltage profile of the system. CSA gives better results as compared to genetic algorithm (GA) in both without and with SVC conditions.

“…The installation of wind energy stations in electrical networks has provided many benefits such as improving the environment, reliability, reducing, voltage instability [1,2] and stabilizing energy prices [3,4]. The improper allocation of wind farms may increase the losses in the power system network [5].Wind power plants will provide a better alternative for compensate the power deficit of electrical grids as compared with large scale hydro and thermal units.…”

The structure, operation, and planning of electric power networks will undergo considerable and rapid changes due to increased global energy consumption. The requirement of renewable energy sources due to the increase of electrical demand. This paper presents wind energy integration with electrical grid under impact on sudden load conditions. To fill the demand and supply gap requires reactive power. To compensate reactive power more prominent devices are needed. The Static Synchronous Series Compensator (SSSC), Static Synchronous Compensator (STATCOM) and Unified power flow controller (UPFC) are the members of the Flexible AC Transmission system family having very attractive features of series and shunt reactive power compensating devices. The proposed research work is carried by wavelet multi resolution analysis using Bior1.5 mother wavelet under Power Quality issue of sudden load 150MW is introduced at bus-3, which can be compensated by a wind energy source and FACTS devices. The analysis of 5-bus network model of sudden load impact is tested and observed that the effectiveness of the system with Wind Energy source integration in presence of SSSC, STATCOM &UPFC.
