Energy storage and hydrogen production combined supply system, coupling control method thereof and storage medium

Abstract

The invention discloses an energy storage and hydrogen production combined supply system and a coupling control method thereof, and a storage medium. The coupling control method comprises the following steps: receiving a scheduling signal; and adjusting first operation power of energy storage equipment and / or second operation power of hydrogen production equipment at least according to the scheduling signal, so that the sum of the first operation power and the second operation power is equal to target power indicated by the scheduling signal. According to the scheme, the service life of equipment can be prolonged while power auxiliary service is provided, the power consumption cost during charging and hydrogen production is low, new energy waste electricity can be reduced, and deployment of the energy storage and hydrogen production combined supply system is flexible.

Description

technical field [0001] The invention relates to the technical field of electric power assistance and energy storage coupled hydrogen production, in particular to a combined energy storage and hydrogen production system, a coupling control method and a storage medium thereof. Background technique [0002] With the development of clean energy and the transition to low-carbon energy, the installed capacity of new energy power generation such as photovoltaic power generation and wind power generation has grown rapidly. However, both photovoltaic power generation and wind power generation have volatility and intermittent problems, which pose challenges to the safe and reliable operation of the power system, resulting in the need for more auxiliary services for peak regulation and frequency regulation in the daily power grid. [0003] On the other hand, in order to ensure that clean energy in the northwest region can be effectively transmitted to the developed regions in the east,...

Problems solved by technology

However, due to the characteristics of frequency modulation signals, lithium battery energy storage needs to be frequently charged and discharged when participating in frequency modulation auxiliary services, resulting in rapid degradation of battery performance and seriously damaging battery life.

Moreover, lithium battery energy storage must depend on the layout of power plants, and there are large limitations and many restrictions on deployment

[0006] To sum up, the performance of existing energy storage power stations is too fast and the cost is high in the process of participating in the auxiliary service of power peak regulation and frequency regulation
