Zero Energy Building by Multicarrier Energy Systems including Hydro, Wind, Solar, and Hydrogen

Abstract

This paper proposes a unified solution to address the energy issues in net zero energy building (ZEB), as a new contribution to earlier studies. The multi-carrier energy system including hydro-wind-solar-hydrogen-methane-carbon dioxidethermal energies is integrated and modeled in ZEB. The electrical sector is supplied by hydro-wind-solar, combined heat and power (CHP), and pumped hydro storage (PHS). The thermal sector is supplied by CHP, thermal boiler and electric heating. The hydrogen storage system and Methanation process operate as the interface energy carriers between the electrical and thermal sectors. The carbon dioxide (CO2) of the ZEB is captured and fed into the Methanation process. The purpose is minimizing the released CO2 to the atmosphere while all the electrical-thermal load demands are successfully supplied considering events and disruptions. The model improves simultaneously the energy resilience and minimizes the environmental pollutions. The results demonstrate that the developed model reduces the CO2 pollution by about 33451 kg per year. The model is a resilient energy system that can handle all failures of components. The model can efficiently handle 26% increment in the electrical loads and 110% increment in the thermal loads.

Optimal Coordinated Dispatching Strategy of Multi-Sources Power System with Wind, Hydro and Thermal Power Based on CVaR in Typhoon Environment

“…The upper and lower limitations of storage capacity and power output are shown in Equations ( 19) and (20), respectively. The reservoir capacity of the hydropower station is dynamically adjusted with natural runoff, discharge volume of upstream reservoirs, and reservoir discharge volume at each dispatching time, and the dynamic change process of reservoir capacity is shown in Equaiton ( 21) [47].…”

Optimization of Multi-Energy Microgrid Operation in the Presence of PV, Heterogeneous Energy Storage and Integrated Demand Response

“…For instance, certain authors proposed a comprehensive model to decide the component capacities in an integrated energy system for a Swedish building, considering the system planning and system operation simultaneously [4]. In [5], the multi-carrier energy system, including hydro-wind-solar-hydrogen-methane-carbon dioxide-thermal energies, are integrated and modeled in a zero-energy building. The authors of [6] proposed the optimization configuration of a regional integrated energy system based on typical residential area modules and typical commercial modules built on actual regional plots.…”

Resilient control of hybrid microgrid with harmonic‐unbalanced loads under outages and faults

“…Nowadays, due to the population growth and the need for electricity on the one hand and the difficulties of electricity generation and transmission on the other hand, the domestic and industrial microgrids are rapidly developed [1]. The microgrids eliminate the costs associated with electricity transmission, reduce the costs of electricity generation and decrease the environmental pollutions [2]. The microgrid includes a set of distributed generations such as wind turbines, diesel generators, fuel cells, photovoltaic systems, and energy storage devices that are utilized to supply the electrical and thermal loads [3].…”
