Abstract An integrated energy system combines the power grid, natural gas pipeline, district heating network, and renewable energy generation to enhance the integration of renewable energy and smooth the load demand profile. However, the system faces great uncertainty derived from flexible renewable generation and demand load, etc. This paper brought in the robust optimization theory, considered the wind power integration on the supply side and the load fluctuation on the demand side. It also co...

Abstract This paper presents and demonstrates, by numerical simulation, a mixed-integer linear programming (MILP)-based Model Predictive Control (MPC) strategy for space-heating demand in buildings connected to a district heating system. The proposed MPC deals with space-heating demand with extended flexibility. It exploits thermal inertia, inherently present in the building and its heating system, to optimally plan space-heating load in anticipation of weather conditions and energy cost variati...

Abstract Wind energy sources have created new challenges in power system scheduling to follow the network load. Gas fired units with high ramping could better deal with inherent uncertainties of wind power compared to other power generation sources. The natural gas system constraints affect the flexibility of natural gas-fired power plants in the electrical market. In this paper, three solutions have been proposed to cover the challenges of gas system constraints and the uncertainty of wind powe...

Abstract Efforts towards ensuring clean and affordable electricity for all have been progressing slowly in rural, off grid areas of developing countries. In this context, hybrid microgrids may offer reliable and potentially clean electricity for isolated locations. Nevertheless, the process of planning and operation of these systems faces several challenges, often due to the uncertainties related to the renewable resources and to the stochastic nature of electricity consumption in rural contexts...

Abstract Using cold latent heat thermal energy storage (LHTES) in cold chain logistics can improve the energy efficiency. In this study, a shape-stabilized phase change material (PCM) with dodecane as PCM and expanded graphite (EG) as skeleton was developed firstly. The optimal content of EG in composite was confirmed as 16 wt% by heat treatment and DSC testing. The DSC testing results show that dodecane/EG shape-stabilized PCM has a phase change temperature of −9.67 °C and latent heat of 151.7 ...

Abstract The relationship between CO2 emissions and economic growth is well-examined. However, there is a gap in the literature to examine the nexus by regime-switching models. For this purpose, this paper examines the interdependence relations between CO2 emissions and the industrial production index as a measure of business cycles at the monthly frequency in the United States. We use a new approach to modeling dependence between the underlying variables over time, combining the time-varying co...

Abstract Gas turbines are a mature technology and any increase in their efficiency comes at high R&D cost. Pressure Gain Combustion (PGC) has emerged as a concept to significantly improve their efficiency. Technically, PGC is realized through detonative combustion or approximations of constant volume combustion. The latter include pulsed resonant combustion and shockless explosion combustion. Detonation combustion is typically realized as pulsed or rotating detonation combustion. Gas turbine pro...

Abstract Hemicellulose is the most reactive component of biomass during torrefaction. Torrefied hemicellulose will be one of the most significant factors determining the reactivity of torrefied biomass during subsequent pyrolysis and CO2 gasification. Xylan, as the representative for hemicellulose, was torrefied in a bench scale tubular reactor with varying torrefaction temperature and residence time. The results demonstrated that the pyrolysis and CO2 gasification reactivity of xylan and its de...

Abstract This paper presents the experimental performance analysis of a latent heat thermal energy storage system (LHTESS) designed for domestic hot water (DHW) applications. The designed, fabricated and characterised thermal store comprised of a vertically oriented multi-pass tube heat exchanger in a rectangular cross-section container filled with phase change material (PCM) paraffin wax RT44HC. The experimental investigation evaluated the heat transfer within the system, measured the transient ...

Abstract Large-scale building energy efficiency retrofit (LSBEER) involves a large number of buildings with heterogeneous characteristics. Decision-making with regard to multiple-technology portfolios, optimal implementation strategy, and regional subsidy policy is a challenging task, made particularly difficult by the presence of various uncertainties. This paper proposes a techno-economic-risk decision making methodology (TERDMM) based on Monte Carlo (MC) simulation, as well as a novel multi-a...
