Liability subject transaction strategy optimization method, system, device and medium

The invention relates to the technical field of power systems, in particular to a responsibility subject transaction strategy optimization method, system and device and a medium. The method comprises the following steps: firstly, representing a responsibility subject market environment, constructing a multivariable MHSA-TCN network, and predicting to obtain monthly average prices of different subject matters in different markets; secondly, constructing a model for predicting the daily electricity demand quantity of the responsibility subject, and predicting daily electricity demand quantity statistics to obtain monthly electricity demand quantity; and then taking the renewable energy assessment index as a constraint condition, constructing a responsibility subject annual monthly transaction strategy model, and finally constructing a particle swarm algorithm model to solve the monthly transaction strategy model to obtain a purchase quantity distribution scheme. The problem of how to complete the RPS assessment
