Traditional energy consumption is continuously decreasing, and new energy demand industries are continuously increasing. Full consumption of clean and renewable energy and efficient utilization of comprehensive energy will become the development trend of energy industry. The smart energy Internet based on the physical structure of the energy Internet is sweeping the world. Using smart and green to fundamentally change the existing energy structure and to adjust the structure dominated by fossil energy to a new energy structure dominated by renewable energy is of far-reaching significance to China’s energy transformation and upgrading in the future. This paper aims at the design idea of smart energy Internet rack for the newly-built ChengBi campus in Baise University, combines peak-valley electricity price and photovoltaic hydrogen production technology to stabilize the fluctuation of renewable energy output, and realizes the safe and stable operation of a comprehensive energy system of distributed photovoltaic power stations. A campus smart energy Internet system is formed by “wind power + photovoltaic + energy storage + charging pile + photovoltaic hydrogen production”.

Establishment of a safety evaluation method is one of the key issues for the nuclear hydrogen production demonstration since fundamental differences in the safety philosophy between nuclear plants and chemical plants exist. In the present study, a practical safety evaluation method, which enables to design, construct and operate hydrogen production plants under conventional chemical plant standards, is proposed. An event identification for the HTTR-IS nuclear hydrogen production system is conducted in order to select abnormal events which would change the scenario and quantitative results of the evaluation items from the existing HTTR safety evaluation. In addition, a safety analysis is performed for the identified events. The results of safety analysis for the indentified five Anticipated Operational Occurrences (AOOs) and three ACciDents (ACDs) show that evaluation items such as a primary cooling system pressure, temperatures of heat transfer tubes at pressure boundary, etc., do not exceed the acceptance criteria during the scenario. In addition, the increase of peak fuel temperature is small in the most severe case, and therefore the reactor core was not damaged and cooled sufficiently. These results will contribute to the safety review from the government and demonstration of the nuclear production of hydrogen.

Abstract Multi-terminal DC (MTDC) hydrogen production systems are becoming one of the important forms of power distribution systems with the increasing growth of distributed renewable energy sources (such as PV and wind turbines), energy storage devices, and DC loads. To explore the key factors in stability analysis, the circuit diagram of MTDC hydrogen production system in hand-in-hand structure composed of voltage source converters (VSCs), DC lines, renewable energy and DC hydrogen production load was established in this paper. The overall state space model of the system was put forward, taking the master-slave converter control strategy into consideration. Then, the small-signal stability analysis of the MTDC hydrogen production system was carried out by comparing and analyzing the moving trajectories of the dominant eigenvalues in different system parameters. The key factor affecting the stability of the system such as DC capacitance of the converter and the electrolyzer power in the DC bus are determined. On this basis, a simulation model of the low-voltage MTDC hydrogen production system was built based on MATLAB/Simulink to verify the correctness of the theoretical analysis.
