Effects of Load Dynamics on a Solar Photovoltaic Panel Fed Power Electronic System
Keywords:
Constant power load, stability analysis, slow-scale instability, negative impedance instability, dc microgrid, boost converterAbstract
One fundamental impact of change in energy mix is the increasing penetration of power
electronic systems in the microgrid and main grid. For cascaded-power electronic converters, closely
controlled downstream converters function as a constant energy load (CPL) to the upstream converters.
A practical load in power electronic system consists of different combinations of constant power,
impedance, voltage and current sources. This paper addresses the complex conduction and control of a
power tracking system by the solar photovoltaic booster converter connected to a mixture of linear and
non-linear stable power load .. The nonlinear modeling is shifted to nonlinearity in source, load, power
and electronics. One striking observation is the absence of the commonly observed fast-scale perioddoubling bifurcation reported previously in similar systems. Bifurcation diagrams have been plotted in
terms of load parameters to indicate a panoramic view of system’s behavior. Chaotic, DCM, slow-scale
and negative impedance instability have been observed.
