Abstract:
Upon various renewable based power generation,
Solar Photovoltaic (PV) technology is continually developing
nowadays. However, the major drawback of this technology is the
intermittent issue due to the rapid fluctuations in solar insolation
level. Energy storage systems such as batteries and super
capacitor banks are used to reduce the above problem. There is a
requirement of an integrated controller strategy in order to
achieve a power generation unit which includes power share
among those energy storage units in between with solar PV array.
Using a hybrid system of a battery bank and a super-capacitor
bank over using a battery bank alone, helps to increase the
lifetime of the batteries. Integrated control strategy is the
common method used to control the solar PV array with energy
storage units in order to supply the required islanded demand and
supply excess energy to the grid while maintaining the DC-link
stability through the synchronized control of DC-DC power
electronic converters. This paper presents an integrated control
strategy for grid connected PV array together with a battery bank
and a super-capacitor bank. This further state mathematical
proof for the sizing of storage devices. Performance of the
integrated control strategy was evaluated using a practical
experiment by developing customized DC-DC power electronic
converters.
