| Summary: | With the rapid development of the economy and society, global consumption of
energy shows continuous increase. However, fossil fuel resources on earth are finite
and therefore with the depletion of the fuel resources, new and sustainable resource
to substitute for the fossil fuels will be needed. Due to their clean, renewable and
environmental-friendly characteristics, solar energy can be actively considered.
In power system, the most common operating mode of photovoltaic (PV) generators
is that of maximum power point tracking (MPPT). Unfortunately, with MPPT, the
PV generators are unable to provide additional power when there is a need to provide
power support for voltage stabilization during system disturbances.
As MPPT is affected through the use of power converters, this project shall examine
the potential of achieving voltage regulation by allowing the PV generators to
operate at non-MPPT mode. By operating at less than the maximum power level, the
PV would have the reserves which can be used to regulate network voltage. This will
c3ll for a redesign of the converter control scheme to emulate the function of
conventional power generators so as to achieve rapid voltage regulation. |
