Optimal operating control strategy for biogas generation under electricity spot market

Abstract

This study presents an approach of biogas generation coupled with electricity trading under electricity spot market to maximise the biogas power profits. The aim of this study is to achieve a minimal generation cost for the biogas generation system while eliminating the dependence on batteries due to the storage and tunable properties of biogas digester. In terms of the electricity prices at different times in the spot market, the operating control strategy for biogas generation is established to perform the optimal generation scheduling, which give the two model comparison results. The practical case of biogas engineering in the ecological park in Hunan Province in China is carried out to validate the effectiveness and practicability of the proposed strategy.
