A Grid-Connected PV Power System Total Considers the MPPT and SSRF-SPLL Control Technologies

Published by Liu Liqun, Liu Chunxia*, Taiyuan University of Science & Technology Abstract. At present, an optimal maximum power tracking (MPPT) and grid-connected control methods for a PV power system are very important to improve the output efficiency. However, most of literatures only introduce the MPPT or PLL method, respectively. A novel MPPT method isContinue reading “A Grid-Connected PV Power System Total Considers the MPPT and SSRF-SPLL Control Technologies”
