In this paper, we reviewed the new MPPT (Maximum Power Point Tracking) Standard ‘EN50530’and tested efficiencies of the ‘Dynamic MPPT’ by using conventional algorithms.
As mentioned in test results, conventional MPPT algorithms showed low efficiencies for dynamic MPPT because of the maximum power point tracking failed.
Therefore we performed test in same condition and procedure with changed step gain to improve the efficiencies because MPPT algorithm with high step gain generally has high efficiency when the irradiance rapidly changes.
As a result we checked test results which showed the high MPPT efficiencies in case of high step gain and the increasing oscillations. And the reverse case indicated the opposite test results.
Therefore in this paper, we proposed the new MPPT algorithm, improved InCond algorithm, to draw a higher MPPT efficiency compared with conventional MPPT algorithms in EN50530 testing standard.
The proposed algorithm tracked the maximum power point using a method that is utilized variations of VMPP (Voltage in maximum power point) and PMPP (Power in maximum power point) according to changing the irradiance by changing a direction and step gain for MPPT.
We could verify that the proposed algorithm rapidly tracked a maximum power point with high step gain when irradiance was sharply changed and showed high MPPT efficiency in case of the stable irradiance condition by performing a slow MPPT with low step gain through the test in EN50530 standard.
