A Comprehensive MPPT Algorithm of the Solar Batteries Energy-Saving Control System

Abstract

The comprehensive MPPT algorithm, which is combined with three approaches including the constant voltage tracking method (CVT), the perturbation and observation method (P&O), and the incremental node-voltage conductance method (INC), aims to study how to improve the solar energy utilization of the solar battery energy-saving control system of field monitoring equipment. To obtain the parameters needed for numerical simulation, solar power meter is used to measure light intensity curve within 30 seconds in spring. Then we establish the photovoltaic array simulation model and get the power tracking curve. Comparing with the curves based on the comprehensive MPPT algorithm with the mainstream MPPT algorithms, its proven that the time consumption of tracking MPP is shorter and that the efficiency of photovoltaic power generation is higher.
