A generic model of a virtual power station consisting of small scale energy zones

The main aim of the research carried out at Durham University is to increase the value of Small Scale Embedded Generators (SSEG) by aggregating and controlling their outputs and grouping them in zones, where controllable load and energy storage devices could be also present. The value is determined by measuring their ability to interact with the electricity market effectively, displace fossil fuel plant, reduce network losses and contribute to power system operational tasks. This paper presents a PSCAD/EMTDC model of a Virtual Power Station (VPS) consisting of Small Scale Energy Zones (SSEZs) connected to the Low Voltage (LV) distribution network. A SSEZ is defined as a controllable section of LV network containing a mixture of SSEGs, distributed storage and load [1].
