Multi-energy biogas production plant exploiting electrical market services provision

Abstract

This study presents the results to identify the optimization strategies to exploit the flexibility provided by a biogas production plant. This plant, located in Murcia Este (Spain), is one of seven real-life case studies located in different European countries under analysis in the EU MAGNITUDE project. This facility is a wastewater treatment plant, with the production of biogas resulting from anaerobic digestion. The biogas produced is completely exploited to self-sustain the electricity and heat plant demands. The flexibility provision ability is exploited as ancillary market participation, in particular by manual frequency regulation reserve provision. The model of the plant refers to a base case and to several possible extensions, improving technologies and management strategies. The experimentations carried out are based on six-week datasets, the results show how the plant can successfully provide the market service in the base configuration and in the improvements proposed. The best results are gained with the configuration including a heat storage device which decouples biogas production, heat demand and service provision.
