Along with the times and the increasing number of human population on earth, the need for energy is also getting bigger. Currently, most of the sources of electrical energy used in Indonesia come from fossil energy and only come from one source, namely PLN. Therefore, it is necessary to develop a system that aims to increase the efficiency of energy use by encouraging a reduction in consumer demand for electrical energy so that it can reduce the amount of energy generated and control the behavior of electricity usage to avoid load spikes at certain periods. This study was conducted to analyze the design of the control system and load management (demand side management) located in the Labtek XIV building or Freeport Indonesia Business Research Center School of Business and Management Bandung Institute of Technology (FIBRC SBM ITB). Simulations and tests were carried out to model the behavior of building loads and load shifting on air conditioner loads using Python devices as well as load measurements with several test conditions before and after the implementation of load control and management systems. At the initial stage, Photovoltaic (PV) production modeling was carried out using the PVLIB library and load profile modeling was carried out using three methods, namely Support Vector Regression (SVR), Artificial Neural Network (ANN), and Deep Neural Network (DNN). Load shifting is carried out referring to the modeling results with the lowest error value. The load cover factor (LCF) value before load shifting is 46% and the supply cover factor (SCF) value is 89%. After load shifting, the LCF value becomes 49% and the SCF value becomes 90%, while when entering the battery system, the LCF value becomes 77.5% and the SCF value is 94.6%.
