Frequency Converter for Solar Energy Systems "PODSOLNUKH" - Optimize Efficiency

One of the main functions assigned to the inverter is to ensure the operation of SES at the point of maximum power. The control system of the proposed inverter implements the algorithm of tracking the maximum power of the FEM (Three-point-weight MPPT algorithm) using model predictive control of the SES in real time under different environmental parameters: the level of insolation; ambient air temperature and the state of the working surfaces of solar panels.The SES, along with photo-electric panels, includes inverters that convert DC electric energy produced by the panels into AC of industrial frequency. The inverter is designed to convert DC voltage 1200 (1500) V coming from photovoltaic modules (PV modules) into output alternating voltage 550 (600) V and transfer electrical energy to the external power supply network with a frequency of 50 (60) Hz.
