    This paper presents the Arduino Nano microcontroller based maximum power point tracking (MPPT) solar charge controller. The optimum solar photovoltaic power is extracted using the Perturb and Observe (P&O) MPPT algorithm. Whilst there are many MPPT solar charge controllers available in the market, the Arduino Nano based MPPT solar charge controller is an attractive method for MPPT controller due to its adaptability, simple, cheap, and durable with good performance for remote areas application with cheaper cost than conventional MPPT charge controllers. This system ensures maximum power is harvested from the photovoltaic panel and capable to charge the battery as well as maintain the battery health condition. This will increase the battery lifespan and increases the efficiency of the photovoltaic panel under varying solar insolations. In this paper, the Perturb and Observe (P&O) algorithm method is developed by using an Arduino Nano based MPPT controller for the photovoltaic generation system. The test result has shown the performance of the proposed controller is capable of tracking the photovoltaic maximum power point and extracting the optimum available power whilst charging the battery in the healthy mode.

    In recent years, the advance usages of non-linear loads have led to the serious power quality problem in the distribution system. Non-linear load will inject the current harmonics and cause power quality problem at Point of Common Coupling (PCC). This problem can be improved by using power filter. Power filter can be divided into passive power filter and active power filter. Passive filter is an appropriate solution to solve power quality problem in term of harmonic mitigation due to a simple circuit, low cost and less energy requirement. However, active power filter (APF) is more suitable due to better performance to solve power quality problem for current harmonics issue. This paper focuses in designing the application of a multi-functional grid-connected solar PV system integrated with DSTATCOM by using Instantaneous Reactive Power (PQ) theory controller to mitigate the current harmonics injected by non-linear load at the distribution system. MATLAB/SIMULINK software is used to simulate the performance of the multi-functional GCPV based SAPF according to IEEE Standard 519:2014 which THD of the line current at the Pont of Common Coupling (PCC) should be less than 8%.

    This paper studies the performance of a hybrid conjugate gradient backpropagation (HCGBP) grid-connected solar photovoltaic (GCPV) based DSTATCOM. This paper proposes a hybrid control algorithm of instantaneous reactive power theory and conjugate gradient backpropagation neural network for an application of a grid-connected solar PV (GCPV) based DSTATCOM for three-phase three-wire system. The fundamental weighted value of active power components of load currents, which is necessary for estimating reference source currents, is extracted using a conjugate gradient backpropagation control algorithm. The performance of the proposed control algorithm has reduced the THD of the line current up to 1.32%. It is proven that HCGBP has better efficiency, faster response and easy to implement. The steady-state performance of the three-phase GCPV-DSTATCOM under non-linear load has been analysed through simulation and Hardware-in-loop (HIL) simulation based on real time DSP system using Texas Instrument TI C2000 32-bit microcontroller in MATLAB/Simulink. Furthermore, the simulation results have shown that the THD of the line current at the PCC has reduced less than 8%, according to the IEEE standard 519:2014.

    This paper presents the indicator system status in the distribution network by using the technique voltage stability index with the artificial neural network to predict the power system. Voltage stability is an indicator from value index zero (0) until one (1). The value index zero is no loading in the system bus, where else one is maximum loading in system buses. IEEE 30 bus practical system was used to test and indicator to predict the power system. Using MATLAB to program and develop Artificial Neural Networks (ANN) in distribution networks. The voltage stability indicator was trained by application ANN to predict each bus system's load status. Therefore, the voltage instability will be early to be known by using the prediction ANN. The information stability index is very important in the power system because it helps to solve the major problems in the distribution system power system.

    This paper presents a three-phase three-wire solar photovoltaic (PV) based DSTATCOM that can improve power quality problems. The solar PV system is designed based on peak-sun approach and simulated in HOMER (Hybrid Optimization Model for Electric Renewable) software. The technical and economic feasibility of different combinations of the system sizing are evaluated based on cost of electricity (COE), the net present cost (NPC) and the percentage of excessive electricity produced. The optimum size of PV system the will be able to supply the load with improved power quality features without any additional hardware to the system. The cost of electricity (COE) of the proposed system is still lower than the feed-in tariff (FiT) scheme provided by the government. Thus, the results showed that the proposed system is viable to improve the power quality at the distribution network.

    Solar energy has become the most prominent renewable energy for electrical power generation of the sustainable development agenda. This project focuses on power quality improvement in the low voltage distribution network by using a three-phase three-wire Distributed Static compensator (DSTATCOM) supplied by a single-stage grid-connected solar photovoltaic (GCPV) system. The instantaneous reactive power theory (IRPT) or P-Q theory will be used as the control algorithm of the PV based DSTATCOM to eliminate the harmonic current caused by the non-linear loads in the distribution system. This control method has great impact on the accuracy of the harmonic current and reactive power compensation for harmonic current elimination according to the requirement of THD limit set by IEEE 519-2014. Sizing of the grid-connected solar PV system based DSTATCOM will be presented and capable to deliver the active power demand to the utility grid under variation of solar irradiances. This system is modelled and simulated in the MATLAB/Simulink environment.

    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.
