This project proposes to assess the performance of a novel power electronic asset called the Active Power Control Unit (APCU). The APCU is a technology based on power electronics that can control active and reactive power flows in power lines both at transmission or distribution. The ability to control active and reactive power, provide the APCU with the ability to utilise existing capacity within the network.
The first stage is to provide a technical and commercial assessment (including Cost Benefit Analysis (CBA)) which will inform the feasibility of further deployment. This method was selected in order to greater explore a potentially significant opportunity at relatively low risk and investment levels.
Provide networks with the capability to model the value of APCU technology to drive efficiencies in the way power is driven across transmission boundaries. If the CBA and this feasibility study are positive, then stage 2 of the project will look to deploy the technology – this will be a separate project.
