    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.

    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.

    Solar energy plays an important role in renewable energy generation systems since it is clean, pollution-free sustainable energy as well as the increasing cost-of-electricity which causes high-growth demands amongst utility customers. This paper presents various circuit topologies of DC-DC converters in solar photovoltaic (PV) applications. There are three types of DC-DC converter presented in this paper that can be integrated with solar PV system which are buck, boost and buck-boost converter in various applications. This paper also presents the application on DC-DC converter in solar PV system for maximum power point tracking (MPPT) feature. The advantages and disadvantages of each topology will be discussed further in term of cost, components, efficiency and limitations.
