This paper presents a methodology for substation data analysis based on the application of a series of data analysis methods aimed at three main objectives: the characterization of demand by identifying different types of consumption, the statistical analysis of the. Monitoring power consumption in a distribution system is a key task for energy management, as it helps to optimize efficiency, reliability, and quality of service. Power consumption is the amount of electrical energy that is used by the loads connected to the distribution system, such as. Crude oil, gasoline, heating oil, diesel, propane, and other liquids including biofuels and natural gas liquids. Exploration and reserves, storage, imports and exports, production, prices, sales. Sales, revenue and prices, power plants, fuel use, stocks, generation, trade, demand & emissions. Measurements of voltage, current and phase-angle as well as calculation of overall box power consumption are conducted in real-time. It is usual to use a time resolution of one hour, with 24 slots, although it is not. It specifies key considerations for carrying out energy consumption analysis, BIT's recommended methodology, and alternative methodologies.
