Description

technical field [0001] The invention relates to the technical field of operation stability of multi-energy systems, in particular to a method for calculating the operation stability of multi-energy systems based on big data. Background technique [0002] With the advancement of scientific and technological means, the user's demand for energy consumption is showing an increasing trend year by year. Traditional technical processing methods cannot avoid the occurrence of excessive extraction of energy consumption resources, and the serious problem of disordered order of regenerative energy has a negative impact on the system itself. The operation stability has a great impact, so it is particularly important to calculate the operation stability of the multi-energy system. Load frequency control technology is one of the most common methods to realize stability calculation. The information transmission of load frequency control is realized through an open communication network. D...
