Most loads on an electrical network are reactive and have a lagging power factor, this reactive power is mostly supplied from the electricity generators and needs to be transmitted through the network just like any other load. The transmission of this reactive power also increases losses and causes unnecessary heating in infrastructure.

An increase in Photovoltaic (PV) penetration in an electrical system has imposed several Power Quality (PQ) and voltage stability issues, the intermittent nature of solar generation mean there is a variable output of power to the system which leads to power imbalance issues and voltage sags and swells. A solution to this may in fact lie in the problem, there is a potential for the installed inverters associated with these systems to be utilised to improve local power quality by supplying or absorbing reactive power, day or night. Currently inverters are only being utilised during daylight hours, leaving an expensive piece of equipment lying dormant for the majority of a day.

This research outlines the gathering of relevant information, compiles a feasibility assessment and documents expected outcomes and benefits. A research methodology is provided together with a risk assessment, project schedule and quality assurance plan and timeline.

This research will provide useful information into the feasibility of grid controlled Static Compensator (STATCOM) inverters and the benefits this would have on power factor and subsequently voltage regulation to the immediate network.
