The invention belongs to the field of power systems, and discloses a method and system for participating electrolytic aluminum load in power system control, equipment and a medium. The method comprises the following steps: acquiring a regional adjustment demand of a power system; obtaining the adjustment power of an electrolytic aluminum load according to the regional adjustment requirement of thepower system; obtaining and determining the control state of the electrolytic aluminum load according to the operation state of the electrolytic aluminum load; when the control state of the electrolytic aluminum load is a callable state, obtaining the base point power of the electrolytic aluminum load; and superposing the base point power of the electrolytic aluminum load and the adjusting powerof the electrolytic aluminum load to obtain the target power of the electrolytic aluminum load, and controlling the power of the electrolytic aluminum load based on the target power of the electrolytic aluminum load. By adding the electrolytic aluminum load, the power regulation capability of the regional power system is improved, and the electrolytic aluminum load receives a unified scheduling instruction, so that the problems that the regulation capability of power control of the power system is limited, and the risks of over-regulation, under-regulation and regulation conflicts are relatively high are solved.
Description
technical field [0001] The invention belongs to the field of power systems, and relates to a method, system, equipment and medium for electrolytic aluminum loads participating in power system control. Background technique [0002] Real-time power balance is the key to the safe operation of the system. In the multi-regional interconnected AC power system, the method of sub-regional control is often adopted to realize the power balance of each region, while taking into account the power support for adjacent regions, so as to realize the overall AC power balance. System power balance. In order to maintain the power stability of the regional power system and reduce the exchange power deviation, the power system introduces automatic power control (AGC) technology, which realizes the balance of system power generation and consumption by adjusting the power of generator sets. Demand response technology is a means for all kinds of adjustable resources to participate in system regul...
