Abstract

Solar power is one of the most useful renewable energy sources. It can generate electric energy and is reliable and non-polluting. The process of turning sunlight into electricity is known as solar power. Solar panels are constructed by connecting solar cells. Direct Current is produced by solar cells (DC). DC power is transformed into AC power by inverters and it is used in AC power applications. Using photovoltaic (PV) technology, solar energy may be converted directly into electricity. Partial shading condition is when a few PV panels in an array are partially shaded and receive less sunlight than other PV panels. To enhance the power supply to the load in partial shading conditions, interconnection techniques such as uneven row shading, uneven column shading, diagonal shading, random shading, and short and narrow shading are utilized. A crucial component of a PV system is Maximum Power Point Tracking (MPPT), which enables maximum energy to be harvested at maximum power point (MPP). The duty cycle of the power converter switch is always adjusted with MPPT algorithm to drive the solar panel continuously at the MPP. A converter acts as an interface between the Solar PV array and voltage source Inverter (VSI). The Landsman Converter is designed to operate in Continuous Conduction mode (CCM) irrespective of the variation in irradiance level. Landsman converter is used to provide a positive voltage from any input voltage. The Brushless Direct Current (BLDC) motor has become a popular option for a variety of industrial drive requirements. High torque, high speed, and high efficiency are the three main characteristics of BLDC motors. To improve the efficiency of the solar PV system under Partial Shading conditions different hybrid optimization MPPT techniques are used. In Incremental Conductance-Enhanced Particle Swarm Optimization (IC-iv newline newlineEPSO) the solar PV module is used for studying the effect of temperature and irradiance on the performance of the PV module.
