Development and demonstration of a system that enables PV sun-tracking installations to supply ancillary services to the grid

An innovative, cost-effective and easy to install technology is introduced that allows PV sun-tracking systems to regulate their production according to the demand. This technology combines both control-automation and communication tools, in order to adjust the PV power production to the consumers, to the needs of the electricity grid operator and to the power market. The main idea is to use the sun-tracking system, i.e. by changing the position of slave trackers, for achieving not the maximum possible power output but the desired one. The proposed system is also able to calculate the maximum power and measure the lost power, therefore enabling charging and market integration potential. The system can be adjusted to almost all sun-tracking systems, whereas the signal transmission towards the PV system can be accomplished both by Digital Audio Broadcasting (DAB) energy data transmission protocol and by ripple control.
