Simulation of energy consumption and load prediction analysis of a 110 kV substation building

The energy consumption of a typical 110 kV substation is simulated with EnergyPlus, and the energy consumption of the substation in summer and winter is analysed. The results show that the energy consumption of the substation building mainly includes the energy consumption of the substation equipment, air conditioning system and fans. In addition to substation equipment energy consumption, air conditioning system energy consumption accounts for the most. Combined with the simulation data, the LSTM model is used to predict the load of the substation,and the results show that the LSTM load prediction model is more accurate when the building energy consumption and meteorological parameters are used as multiple inputs. The prediction results are most accurate and the model performance is the best when the hyperparameters are set to time_step=33 and rnn_unit=256.
