Solar Power Optimizer for DC Distribution System
Journal Title: GRD Journal for Engineering - Year 2017, Vol 2, Issue 4
Abstract
Solar Power Optimizer(SPO) for DC Distribution System comprises of a high step-up solar power optimizer (SPO) which efficiently harvests maximum energy from a photovoltaic (PV) panel, energy is output to a dc-micro grid. It integrates coupled inductor and switched capacitor technologies to realize high step-up voltage gain. The leakage inductance energy of the coupled inductor can be recycled to reduce power losses and voltage stress. A low low-conduction resistance and voltage rating switch improves system efficiency by employing the fuzzy logic method for the (MPPT) maximum power point tracking algorithm. It has high tracking accuracy, hence the method is widely used to harvest energy of PV systems. The reduction in power caused by the existing shadow effect on PV panels is an unavoidable problem in a centralized PV system. The use of a micro inverter or ac module has recently been proposed for individual PV panels.
