“…While the work of Uris et al [163] was correlated to the optimisation of scale and configuration of CHP designed to meet the district-wide thermal load in Spain, Ren et al [164] analysed the most economically effective allocations of solar-assisted CHP system allocation (based on gas turbine and gas engine selection) for public, residential, and mixed building complexes in five cities with differentiated climate characteristics. Wang et al [161] on the other hand emphasised on minimising the environmental impact in resource allocation design and scaling of natural gas-based combined cooling, heating and power (CCHP) plant with solar PV and thermal systems. Zhang et al [162] extended the work by simultaneously minimising the environmental impact and overall cost for the design of CHP-based microgrid system comprising of ICE, SE, proton-exchange membrane (PEM) fuel cell, solid oxide fuel cell (SOFC), TES, and condensing boiler.…”

a b s t r a c tThis paper construct a CCHP and renewable energy based hybrid energy system driven by distributed energy resources (DERs CCHP). Then, the paper constructs performance indexes from energy, economic and environment. Thirdly, the paper proposes a multi-objective optimization model for DERs CCHP system under four optimization of energy rate (ER), total operation cost (TOC), carbon dioxide emission reductions (CER) and joint optimization. Finally, Guangzhou Higher Education Mega Center (GHEMC) in China is taken as the object for comparatively analyzing the operation performance of DERs CCHP system and CCHP system driven by natural gas (NG CCHP system). Results show: Joint optimization mode could balance the results of different optimization modes. DERs CCHP system shows better operation performance. ER of ER optimization, CER optimization and joint optimization are higher than that of NG CCHP system. NPV of all optimization modes is positive, IRR are bigger than the expected yield rate. DERs CCHP system could reduce CO 2 emission by utilizing wind energy and solar energy to replace NG. The sensitivity analysis indicates the performance of the DERs CCHP system will become better with the increase of chiller COP, decrease of NG price and wind-photovoltaic equipment cost.

“…Some interesting works that have thoroughly approached CO 2 emissions include the life cycle assessment (LCA) optimization of a solarassisted hybrid CCHP system, 29 the multiobjective optimizations based on economic and environmental aspects of a renewable hybrid CHP system 30 and a CCHP system, 31 and the techno-economic and environmental design of small-scale microgrids. This not only results in an imbalance between the economic and the environmental aspects, in which the former is assessed for both investment and operation costs, while the latter only accounts for operation emissions, but also compromises the accuracy of the environmental optimal, in which technologies are installed as if they had no environmental impact whatsoever.…”

This paper develops a multiperiod multiobjective optimization procedure to determine the optimal configuration and operational strategy of a trigeneration system assisted with solar-based technologies and thermal energy storage. The optimization model, formulated as mixed integer linear programming problem, incorporates dynamic operating conditions through time-dependent local climatic data, energy resources, energy demands, electricity prices, and electricity CO 2 emission factors. The methodology is applied to a case study of a residential building in Spain. First, the single-objective solutions are obtained, highlighting their fundamental differences regarding the installation of cogeneration (included in the optimal total annual cost solution) and solar-based technologies (included in the optimal total annual CO 2 emissions solution). Then, the Pareto curve is generated, and a decision-making approach is proposed to select the preferred trade-off solutions based on the marginal cost of CO 2 emissions saved. Additionally, sensitivity analyses are performed to investigate the influence of key parameters concerning energy resources prices, investment costs, and rooftop area. The analyses of the trade-off solutions verify the enormous potential for CO 2 emissions reduction, which can reach 32.3% with only 1.1% higher costs by displacing cogeneration in favor of the heat pump and the electric grid. Besides, with a modest cost increase of 7.3%, photovoltaic panels are incorporated, promoting an even greater CO 2 emissions reduction of 45.2%.
