Embodiment Construction

[0100] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0101] The present invention further considers the hydrogen demand on the basis of the electricity, heat and cold demand of the regional integrated energy system itself. In addition, hydrogen energy is easier to achieve large-capacity and long-term energy storage than electric energy. Therefore, the present invention establishes a mathematical model for interseasonal hydrogen storage equipment, which can realize interseasonal storage of hydrogen energy and effectively improve the overall economics of the system.

[0102] like figure 1 As shown, the comprehensive energy system of electricity and hydrogen considering seasonal hydrogen storage includes fans, photovoltaics, electrolyzers, gas turbines, electric boilers, batteries, heat storage tanks, hydrogen storage tanks, cross-seasonal hydrogen storage equipment, abs...

Abstract

The invention discloses an electric hydrogen comprehensive energy system considering seasonal hydrogen storage and a robust planning method thereof, and the method comprises the steps: establishing across-seasonal hydrogen storage model, and enabling the model to achieve the cross-seasonal complementation according to the difference of renewable energy output and multi-energy demands in differentseasons; secondly, performing modeling on a gas turbine, a draught fan, a photovoltaic device, an energy storage device and the like, and therefore forming the electricity-hydrogen comprehensive energy system with the multi-energy requirements of electricity, heat, cold, hydrogen and the like. According to the three-layer min-max-min robust programming model considering renewable energy output uncertainty, the inner layer adopts a 0-1 variable to represent a cross-seasonal storage charging and discharging state, so that the model needs to be solved by adopting an N-C & CG algorithm. Results show that the method effectively improves the renewable energy permeation level of the electric hydrogen comprehensive energy system, and improves the system economy.

Description

technical field [0001] The invention belongs to the application field of comprehensive energy systems, and specifically relates to an electric-hydrogen comprehensive energy system considering seasonal hydrogen storage and a robust planning method thereof. Background technique [0002] The regional integrated energy system plays an important role in improving energy utilization efficiency, promoting the development and utilization of renewable energy, reducing greenhouse gas emissions, and improving the living environment. With the development of fuel cell technology and electric hydrogen production technology, the development of hydrogen energy in the field of transportation has become increasingly prominent. In addition, hydrogen energy is easier to achieve large-capacity and long-term energy storage than electric energy. The existing regional integrated energy system does not consider the demand for hydrogen, and the overall economy of the system is poor. Contents of th...
