In this review a number of boost converters are studied, responsible for converting a low direct current voltage to a higher magnitude using a number of different methods including coupled inductors, series combination of a capacitor and two parallel inductors and an inductor discharging to two series connected capacitors in transfer of power. The converters encounter two major practical issues sudden rise in di/dt and dv/dt that drastically reduces the efficiency and increases power loss in passive elements and stress in active switches.

They have a very large area of applications ranging from computing to communication. They are widely used in appliance control transportations and high-power transmission. Its increasing demand is based on its capability of electrical energy conversion. The basic topologies of DC-DC converter are Buck converter and Boost converter, other topologies are derived from these two basic topologies. Mathematical modelling of both Buck converters is done. Some of the control schemes are summarized in this paper. Current mode control (CMC), PID, Sliding Mode (SM) control including their advantages and disadvantages are highlighted in this paper.

Areas with high impurity contaminants and high concentration of transition metals have the most number of hot spot heating. When the operating current of the overall series string approaches the short circuit current of a bad cell then the overall current becomes limited by the bad cell. The good cell becomes forward bias, which reverse biases the bad cell. This leads to large dissipation of power in the bad cell. Enormous power is dissipated in the bad cell or hot spot that results in destructive effects like glass cracking, melting of solder or degradation of a solar cell. The solar panel works best when there is no shade on them. If there is a partial shadow in any one of the arrays, the efficiency of the solar panel drops to a great extent. The shaded cell becomes reverse biased so maximum power will be dissipated on the shaded cell. The heat developed due to the reverse biased of the shaded region adds to the dissipated power.

Solar energy will become the ultimate and prime source of energy in near future. Therefore, highly efficient and low energy consuming solar-powered equipment and applications will soon be a major requirement. In this paper, solar charge controller using Maximum Power Point Tracking (MPPT) and Pulse Width Modulation (PWM) have been analyzed and compared, which is needed in all solar powered systems that utilize batteries. Its role is to regulate the power going from the solar panel to the batteries. Most of the modern charge controllers include PWM and MPPT. These charge controllers are designed such that the solar battery gets recharged quickly and does not get over discharged, thereby ensuring the prolonged lifespan of the battery.

As we have limited resources of power generation, it results into heavy loading of the transmission line, which leads to stability, voltage sag/swell and reactive power issues. Application of FACTS controllers in a power system is a promising and more efficient way for transfer and control of a bulk amount of power. This paper focuses on voltage dependency on reactive power and control of the same for improvement in the power quality. A comparative analysis of steady-state power flow control of a power system transmission network using FACTS controllers namely SVC, STATCOM and TCSC are performed. The performance of these FACTS controllers in the control of power flow on a given test bus system is analyzed. Voltage magnitude is compared for shunt-connected controllers to analyze the efficiency. Reactance modeling and power injection modeling techniques are used to incorporate the FACTS controllers into Newton-Raphson load flow algorithm. Numerical results on a benchmark 5 bus test system with incorporation of each of the FACTS controllers are presented.

Energy is critical, and people with no sustainable access to energy are deprived of the opportunity to become part of national and global progress. Sustainable Development Goal 7 (SDG7), as set by the UN General Assembly, aims to correct the enormous imbalance by ensuring everyone has access to affordable, reliable, and modern energy services by the year 2030. In this vein, Assam Don Bosco University, appointed as the Cluster Leader by the International Association of Universities for SDG7 (Affordable & Clean Energy), is organizing an ONLINE International Conference on Emerging Renewable and Modern Energy (ICERME-2021) on 12-13 February 2021, intending to build a coherent sustainable network of relationships among budding researchers, innovators, industry professionals and the intelligentsia to discuss various sustainable energy opportunities for transforming lives, economies and the planet.
