MULTI-OBJECTIVE STORAGE OPERATING STRATEGY FOR INDUSTRIAL MICROGRIDS

White Paper

Industrial companies are often characterized by high consumption of electrical and thermal energy. In Germany, for such large-scale consumers a special electrical power measurement is mandatory for the connection to the supply grid. Depending on this measurement, the energy expense report of such consumers also includes the costs for the maximum power beside the energy, which is different to the billing of small consumers. In particular, when energy storages are used the power shape can be influenced with respect to these specific feature. This paper presents storage operating strategy, which is designed with respect to these special features of "industrial microgrids" to provide a high reduction of the total supply costs of the company. The used methodology is based on the theory of Model Predictive Control and offers a high degree of flexibility and expandability.
