An Optimization Model for Combining Seasonal Pit Thermal Energy Storage and Biomass Trigeneration Energy System

In this paper, an optimization model for incorporating seasonal heat energy storage and biomass trigeneration power plant is presented. Currently in Croatia, overall efficiency of biomass CHP or CCHP has to be above 50% on an annual basis in order to be eligible for a feed-in tariff. Consequently, biomass power plants use the excess heat production for drying biomass which is currently allowed. However, it is expected that it will not be allowed in the future due to inefficient use of heat. Thus, this paper provides a solution for managing excess heat in biomass CHP and CCHP power plants, as well as a way to shave peak energy demand. The objective of the optimization model is to maximize net present value (NPV) using hybrid optimization method. It is a demand driven model, covering real heating and cooling energy need by end-use customers. Optimization model is easy to adopt in different regions and can be used for evaluating economic feasibility of the investment in trigeneration system that covers all heating and cooling energy demand. Two case-studies were done in order to show the impact of minimum allowed overall power plant efficiency on overall economic indicators. Moreover, the financial data for the possible shift from feed-in-tariffs to fixed and variable feed-in-premiums was presented.
