Distribution static compensator is based on power electronic devices technology which is utilized to supply rapid changes in active power as well as reactive power of utility grids. This is useful to achieve corrections in power factor, balancing of load, compensation of current and filtering of harmonics. Therefore, proposed work investigates the improvement of the power quality by utilizing the distribution static compensator, which is equipped by battery energy storage system and interfaced to distribution network with solar photo voltaic (PV) energy integration. In the present study, distribution static compensator is controlled using a control strategy based on the synchronous reference frame theory. Customised IEEE-13 nodes test system incorporating solar PV generation and distribution static compensator, is utilized to perform the harmonic mitigation and power quality analysis. Disturbances of power quality and harmonics have been investigated due to abrupt changes in the insolation of solar radiation, outage of PV plant from grid and synchronization of PV plant to grid. MATLAB/Simulink environment is utilized to perform the study. Effectiveness of a developed approach is validated by comparing results of simulation with results extracted in real time using real time digital simulator. Results indicate that the developed method is more effective for harmonic mitigation and improving power quality of electrical power in distribution network integrated with solar PV generation. Performance of the approach is compared with the performance of methods reported in the literature to establish the suitability of the method for harmonics mitigation and power quality improvement in grid with solar energy. 1 INTRODUCTION In recent years, renewable energy (RE) sources have captured global interests among academic institutions, industries, and governments due to their numerous advantages for improving energy reliability, efficiency, and minimizing carbon emission [1, 2]. RE resources like wind energy and solar photovoltaic (PV) are extensively used for generation of power at the grid level due to their capability of minimum impact on the environment, sustainability, zero fuel cost, minimum operation cost of the plant, and pollution-free electricity generation [3, 4].

“…The RE sources like solar and SOFC generator produces dc output power, the voltage of which is changed to common DC bus voltage by the use of DC-DC boost converter. The inverter is based on power electronics device and used to convert a DC input voltage into constant AC output voltage required at grid level as well as utility load at AC bus of the proposed test system [18], [19]. A desirable AC voltage can be obtained by changing the DC input power, which is available on the DC bus with the help of dc to dc converter and maintaining the gain of the inverter constant.…”

<p>This paper presents an approach for optimal generation capacity mix to fulfill future power demand using a micro-grid model which is operated in both the on-grid and off-grid modes. This is achieved using the solar photovoltaic (PV) system, fuel-cell, and battery energy storage system (BESS) with and without the grid-connected mode. Different control approaches and optimal size of the generators are presented. Proposed micro grid with solar PV system, solid oxide fuel cell (SOFC) and back scattered electron detector (BESD) is tested for different operational scenarios of loads. Comparative index of performance (CIP) is introduced to indicate effectiveness of the micro-grid operations in the off-grid mode. This is based on difference in the total harmonic distortions (THD) in both the on-grid and off-grid modes. This is established that CIP indicates that the micro-grid works efficiently in the both the on-grid and off- grid modes during the simulated events of the switching ON/OFF the loads at different test conditions. The optimal generation mix successfully met the load demand with and without grid having conventional generatio.</p>

“…Equipping the FACTS device with battery energy storage system (BESS) expands its operation by inducing active power to PCC (point of common coupling). During power system transients, FACTS controllers with battery energy storage systems (BESS) [4][5] can stabilize the system with real and reactive power exchange and also can increase the power transfer capability. Conventional power electronic converters with two level output makes much higher voltage stress across the power switches which increase the losses and can even damage the power switches.…”

Power quality is the term that which appears often in electrical terminology. With good quality in power, power system performance increases. Maintaining the power system parameters close to ideal values is power quality. FACTS devices, using power electronic technology, are extremely fine devices to keep the power system well composed. A FACTS device without active energy source is confined in its operation and the addition of energy storage device can make FACTS device to exchange real and reactive power to PCC and can significantly improve the grid performance. The paper illustrates to improve quality in power system with a battery unified DSTATCOM and active power injection to PCC. DSTATCOM is a multi-level device giving out five-level output reducing the stress across the power switches of DSTATCOM. A multi-carrier level shifted carrier PWM technique is used to trigger five-level DSTATCOM. The model is designed as well as simulation results are evaluated by using Computer Simulation platform.
