Virtual power plants with combined heat and power micro-units

The aim of the work is the integration of combined heat and power (CHP) micro-units into the low voltage network under technical and economical point of view. The whole power and gas consumption of a new residential district are measured and recorded in fifteen minutes intervals during one year. Based on these power and gas load curves the basis of a virtual power plant with CHP micro-units is analysed. With a simulation tool the operation of a CHP micro-unit is simulated. The results show the behaviour of single units in different types of houses and of all units in a virtual power plant. Furthermore they show how the operation of a CHP micro-unit must be optimized for the operation in a virtual power plant. On the basis of this technical parameters a business model for an virtual control power plant is presented and calculated.
