“…The p-q theory, also referred as instantaneous reactive power theory, is popular in three-phase threewire power systems and has recently been developed to three-phase four-wire power systems. Despite the fact that this theory utilizes signals of three currents and voltages, the three separate signals can be obtained by lagging or delaying the available single phase signal by 120º and 240º [2], [7]. Load currents for phases B and C can be characterised as equation ( 2) and equation ( 3), respectively, by using equation (1) of the load current for phase A [7].…”

“…However, few researchers have investigated the single-phase grid-integrated PV (GCPV) system under major power quality concerns. This work aims a modified p-q theory control algorithm for a singlephase GCPV-DSTATCOM, which may be accomplished by simulating a three-phase system by generating same magnitudes of two individual currents and voltages according to the measured current and voltage but offset by ±120° [2] [7].…”

This paper investigates the performance of a single-phase grid-integrated photovoltaic based DSTATCOM by using modified p-q theory control algorithm. Previously, p-q theory controller has been employed for a three-phase DSTATCOM system. Thus, this paper employs a modified p-q theory control algorithm for a single-phase grid-integrated solar PV (GCPV) based DSTATCOM. Thus, the GCPV system has improved with DSTATCOM capabilities such as harmonic reduction for a single-phase distribution system under varying solar irradiances. The simulation results have been obtained by using MATLAB/SIMULINK software in accordance with IEEE Standard 519:2014, which stated that the THD should be less than 8% for the line current at the Point of Common Coupling (PCC). The performance of the single-phase GCPV based DSTATCOM has been analysed for dynamic and steady-state conditions under varying solar irradiances.

“…A PV system converts solar energy into electrical energy by exciting electrons in silicon cells, making PV system an intermittent energy source. PV generation coincides with peak energy demand, and provides low maintenance and operation costs, as well as a long service life and positive environmental impact [14]. However, PV cell efficiency is low and power generation is dependent on location and weather conditions.…”

The content of this paper addresses possible approaches that will eventually allow the development of microgrids for small and medium size industries on a massive scale. Therefore, it addresses in a comprehensive way, the most suitable communication technologies for microgrids in this type of enterprises. Several energy sources that can be implemented in industrial microgrids are also briefly addressed, including generation and storage units frequently adopted for power supply in small scale distribution grids. The overview of communication technologies and energy sources takes into account the financial limitations of small enterprises with the purpose of assisting the study of industrial microgrid architectures. In addition, a case study is presented in order to observe how a centralized and a decentralized deployment of energy sources affect the performance of a small or medium scale industrial microgrid. Since this sector is very important for the development of modern societies, it should make use of the most advanced infrastructures in order to be more sustainable, both environmentally and competitively. The practical limitations applied to industrial microgrids (e.g., lack of standards in the grid codes, some unfit technolo gical performance and amiss system design) shows that the subject presented in this paper deserves much more research and developments. Thus, this work demonstrates the importance of the development of the microgrid for the small and medium-sized enterprises sector.

“…In contrast to the above methods, the hysteresis current control (HCC) is a simple method for multi-functional operation as it offers advantages such as rapid current controllability, easy implementation, and load insensitivity with respect to parameter variations, maximum current limit, and better stability [15,16,[23][24][25][26][27][28]. But, the major limitation of the HCC is its highly variable switching frequency to match variation in solar irradiation and associated compensation requirements that results in higher switching losses.…”

Integration of rooftop solar-PV (RTSPV) systems and extensive use of nonlinear loads in the low-voltage distribution system (LVDS) leads to poor power quality (PQ). Therefore, it is necessary to address the issues leading to poor PQ at the point of common coupling of the LVDS. In this article, a multi-band hysteresis current control (MB-HCC) for the multi-functional inverter (MFI) is proposed which improves the efficiency of the MFI and also enhances the PQ of the LVDS. The MB-HCC uses simple switching logic and outperforms in its multi-functional tasks such as active power injection and power conditioning. MB-HCC offers better efficiency over variable double-band HCC (VDB-HCC) as it operates at a lower switching frequency. The performance of the proposed system is simulated by using MATLAB/Simulink and validated by OPAL-RT based real-time simulation studies. During the variation of solar irradiation, the proposed MFI has an average efficiency of 98.5% under the ideal grid and 97.34% under the distorted grid. Moreover, the percentage of Total Harmonic Distortion under ideal and distorted grid conditions is brought down to below 5%, and also, reactive power compensation maintains unity power factor operation complying with the IEEE-519-2014 and 1547 standards. These results substantiate the hypothesis of scalability of the single-phase MB-HCC-based MFI for an LVDS contributing to economy and ecology.
