Peak shaving system and electric power system

The invention relates to a peak regulation system and a power system. The flexibility and balance of the power system are improved by providing an additional peak regulation means. The system comprises a power supply system, a hydrogen production system connected with the power supply system, a chemical engineering system connected with the hydrogen production system, and a peak shaving unit in communication connection with the power supply system, the hydrogen production system and the chemical engineering system, and the hydrogen production system is composed of a plurality of electrolysis subsystems; the peak regulation unit is used for executing the following steps for peak regulation: planning an operation curve according to the control parameters, and starting the hydrogen production system and the chemical system according to the operation curve; real-time operation parameters of the hydrogen production system are obtained, and a plurality of electrolysis subsystems meeting the preset safety risk value
