2015 - 2017

Concepts for demand side management (DSM) in greenhouses are developed that adapt to the increasing generation of electricity based on renewable energy accompanied by high volatility. They must be economically sustainable and ensure stable operating costs of the greenhouses.

A dynamic strategy of the energy management considers the requirements on the power supply for an optimal plant production. Crucial characteristics of the concepts are the utilization of excess energy from renewable sources for variable illumination of plants in greenhouses and the use of buffer capacities by heat storage in water tanks. A cost-benefit analysis assures the optimal rating of production and storage capacities.

The project will be conducted in cooperation with the Fraunhofer Institute for Wind Energy and Energy System Technology and the Albrecht Daniel Thaer-Institute of Agricultural and Horticultural Sciences at the Humboldt University. The project is supported by funds of the Germans Gouvernment’s Special Purpose Fund held at Landwirtschaftliche Rentenbank. At the IGZ we focus on studies on the use of excess capacities in the electric power production of renewable energy for flexible lighting of plants in greenhouses.
