Control of generic virtual power plant

The aim of this project is to analyze and design a Virtual Power Plant (VPP) structure that integrates the use of combined heat and power (CHP) micro units, enabling them to trade power on the general power markets. The dispersed generation units require less energy when altering their production outputs, making them ideal for controlling the power balance in the power grid. The work is done with a technical and economical view on the potential owners of the CHPs and VPP, and what savings they earn by using micro-CHP generated power and heating. Clients are designed and simulated to work in accordance to micro-CHPs already available on the market. A client framework is developed enabling the individual clients to manage their own production in accordance to their connected consumers and the power they sell via the VPP network. The architecture of the VPP is hence very client minded, and each client de-termines how much power it wants to produce and at what price. When the VPP wants to feed power into the grid it sends out a system price, the clients answer back with the amount of power they are willing to produce at the given price. The VPP sorts the clients and enters a bidding round where it controls the bid price until the wished cumulative amount of power is sent out by the clients. A range of tests and a case study of the final VPP with connected clients is as a proof of concept and to illustrate the systems ability to function cor-rectly. The developed framework can function as a template and a starting point for further development and application of a VPP in Denmark con-sisting of decentralized producing units
