“…In [15] a trigeneration system based on SOFC for domestic applications was modelled and then evaluated under the 4-E assessment criteria: energy, exergy, economy, and environment. Depending on these criteria, the system was multi-objectively optimized by following two operation strategies: off-grid following electrical load and on-grid base load operations.…”

In this paper, a new heat recovery for a microcogeneration system based on solid oxide fuel cell and air source heat pump (HP) is presented with the main goal of improving efficiency on energy conversion for a residential building. The novelty of the research work is that exhaust gases after the fuel cell are first used to heat water for heating/domestic water and then mixed with the external air to feed the evaporator of the HP with the aim of increasing energy efficiency of the latter. This system configuration decreases the possibility of freezing of the evaporator as well, which is one of the drawbacks for air source HP in Nordic climates. A parametric analysis of the system is developed by performing simulations varying the external air temperature, air humidity, and fuel cell nominal power. Coefficient of performance (COP) can increase more than 100% when fuel cell electric power is close to its nominal (50 kW), and/or inlet air has a high relative humidity (RH) (close to 100%). Instead, the effect of mixing the exhausted gases with air may be negative (up to −25%) when fuel cell electric power is 20 kW and inlet air has 25% RH. Thermodynamic analysis is carried out to prove energy advantage of such a solution with respect to a traditional one, resulting to be between 39% and 44% in terms of primary energy. The results show that the performance of the air source HP increases considerably during cold season for climates with high RH and for users with high electric power demand.

In recent years, interest in artificial intelligence has been increasing in the energy sector, with the aim of improving efficiency and decreasing overall consumption. Innovative methods such as pattern recognition, artificial neural networks or other machine learning methods are being investigated to improve the accuracy of forecasting. Moreover, a suitable operation strategy may improve the efficiency of energy systems. The electric equivalent load is an operation strategy proposed for systems where electricity and heat (or cooling) are requested simultaneously, and there is equipment such as a heat pump to cover the heating (or cooling) load. In this paper, the electric equivalent load is defined to cover both the electricity request of the user and the electricity consumption of the heat pump. Thus, the energy system follows the electric equivalent load to cover both electricity and heating/cooling requests. This study aims to analyse how the accuracy varies when forecasting energy requests (e.g. electricity and heat) separately with respect to forecasting directly the electric equivalent load. The results show that electric equivalent load forecasting averages the accuracy of electricity and heat, improving the operation system by decreasing the electricity demand from the grid and increasing energy production during peak hours.

“…Optimal energy management based on 4E criteria, namely energy, economic, exergy, and environment, was proposed for SOFC‐based cooling, heating, and energy system. [ 7 ] A previous study applied optimum power performance through a multi‐objective optimization approach to SOFC‐based cooling, heating, and power systems. [ 8 ] Another study implemented optimal operation adjustment for off‐grid polygeneration using a fuzzy mixed‐integer linear programming model.…”

This study focuses on designing an optimum polygeneration system for residential homes employing solid oxide fuel cells as the prime mover. Optimization of system components is conducted through multi‐objective and multi‐criteria combined with decision‐making to define the priority of each criterion used. Genetic algorithm (GA) and particle swarm optimization (PSO) techniques are applied to find the optimum capacity and analytic hierarchy process as the decision‐making method. Based on the results, the combination of GA and analytic hierarchy process (AHP) gets the best non‐dominated solution among the ten solutions generated, superior in power loss and energy cost criteria. The preference design of “energy loss‐energy cost” gets the highest priority rank of 0.188 with an efficiency of 0.797, primary energy saving of 0.651, CS of 0.424, carbon dioxide reduction of 0.626, and loss probability of 0.153. The optimum polygeneration system has higher primary energy‐saving, CS, and carbon dioxide reduction by about 81.29%, 54%, and 99%, respectively, compared to the unoptimized systems.
