Method for the optimal design and control of a geothermal plant

摘要

The invention relates to a method for the optimal design and control of a geothermal plant with more than two geothermal probes. Including a suitable underground model and a suitable load profile, so-called interaction coefficients are first determined by simulating the temperature development in the underground during operation of a geothermal heat exchanger field. These go into a subsequent optimization step, in which optionally by varying the operating strengths of geothermal probes or by varying the positions of the well centers of geothermal probes, the maximum cooling in the ground at any position is minimized. In this way, local temperature anomalies in the ground can be minimized by optimized independent control parameters for the geothermal probes, or by optimized positioning of geothermal probes within the geothermal probe field, resulting in a more efficient operation of geothermal probe fields and thus to extend the life of geothermal systems.
