Harmonic mitigation and power quality improvement in utility grid with solar energy penetration using distribution static compensator

Abstract

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].

Current Status and Future Trends of Power Quality Analysis

“…Papers [5,16] both apply most of the techniques discussed in this review, and [17] exposes a selection of additional techniques, such as KF, HHT, RMS, and HOS. Other authors prefer the combined use of AI with one another technique; this is what happens in the case of [10] with HHT, [18] with RMS, [19] with THD, [6] with HOS, or [8] with ST. Papers [7,20,21] omit the use of other complementary techniques. Indeed, Figure 2 depicts a timeline relationship among analysis procedures and application fields.…”

“…Another interesting observation that can be extracted from the analyzed papers is the source of the signals used to carry out each study. Even though in some cases both real and synthetic/simulated signals are used to corroborate the programming or calculations made [5][6][7][8][9], in most documents just one of the signal types is chosen. Other clear examples of the use of both types of signals are [52][53][54][55][56], applied to PQ analysis with HOS, [57][58][59] for WT analysis, and [60,61] for AI.…”

Comprehensive Approach to Mitigating Solar Photovoltaic Power Penetration Effects in a Microgrid

“…Works in Ref. [31] consider an IEEE 13 nodes test feeder including solar PV generation and distribution static compensator so as to perform harmonic mitigation and power quality analysis. In order to validate the control of the distribution static compensator, several scenarios are considered to investigate disturbances of power quality and harmonics, like insolation of solar radiation, outage of PV plant from grid, and synchronization of PV plant to grid.…”

“…However, our paper has more extremely cases such as 45, 60%, 100%, and 200% compared to 10% [20] as well as tried to analyze on the impact of distributed PV in terms of various indicators as power losses, FVSI, and voltage stability compared with other 3 cases. (iv) A new coordinated voltage control, combining two control techniques using smart inverters and capacitor banks, is implemented with the integration of different indexes like mentioned above, leading to a new control algorithm approach different from the existing methods in the open literature as described in [22,27,31,34]. (v) e studied MG architecture considers real data from Los Angeles, California, such as the weather conditions and commercial building data.…”
