Energy consumption data “appear”, carbon emissions can be seen

With the solid green power supply and distribution “skeleton” of the buried intelligent ring cage, Jiangbei New District power supply Company began to try to create the “spirit” of the green power supply system through the digital energy carbon management software, and finally let the software and hardware complement each other and complement each other to jointly consolidate the low-carbon base of the construction of the smart park.

TC513V1 In the office park of Jiangbei New District Power Supply Company of the State Grid, the installation of 20 kW photovoltaic power generation equipment, 100 kW/ 200 kWh energy storage battery containers and 60 kW charging piles has been completed one after another, but the original energy management system is “helpless” for these renewable energy equipment. Due to the lack of data collection and analysis platform, it is difficult to balance distributed power supply and power load, resulting in energy waste and mismatch between supply and demand, and it is impossible to carry out unified and reasonable scheduling; Secondly, information asymmetry and lack of monitoring means lead to energy use can not be accurately mastered and managed, and energy consumption caused by electrical equipment can not be found and improved in time; In addition, it is not possible to grasp the carbon emission reduction situation of the park in a timely manner, and there is “no evidence to rely on” in implementing low-carbon development policies.

Smart ECX carbon management platform

To this end, the State Grid Jiangbei New District Power TC513V1 Supply Company decided to create a new energy carbon management platform to solve the above problems. Through consultation and demonstration, the State Grid Jiangbei New Area Power Supply Company decided to adopt the privatization deployment method, with the Siemens Smart ECX energy carbon management platform as the core, first quickly and accurately access the existing photovoltaic power generation, energy storage, charging piles and other types of data sources, and then through the platform’s data Kanbian and digital twin technology. Fully demonstrate the use of enterprise energy carbon and microgrid, and further analyze, calculate and optimize scheduling. Later, we can also set energy performance KPI, preset energy periodic report, abnormal work order alarm and other functions to achieve the energy visualization and intelligent management of park load and optical storage and charge, as well as carbon emission management goals, and finally make carbon emissions visual, quantifiable and controllable.

For the energy management system, on the basis of transparency TC513V1 and visualization, a good optimal scheduling strategy is the key to ensure the rational and efficient operation of energy supply and load.

The power supply company has achieved three major optimization goals

Cost first

With the energy forecast data as a reference, calculate the cost and time of electricity consumption, optimize and control the charging and discharging mode of energy storage and charging pile, so as to save money.

Low carbon priority

With the new energy vehicle charging forecast and photovoltaic power generation forecast as reference, calculate the total carbon emissions, optimize the control of energy storage and charging and discharging modes of charging piles, so as to reduce the proportion of electricity consumption in the grid and achieve “greener”.

Demand management

According to the power limit of the transformer connection point set by the user, timely find energy leakage and inefficient equipment, optimize the control of the charge and discharge of energy storage and charging pile, so that the energy use is “not exceeded”.

Through energy monitoring of optical storage and charging facilities and predictive analytics based on big data, we can better achieve ‘cloud-edge’ collaboration and improve energy efficiency, thereby reducing overall energy consumption and carbon emissions. According to the annual photovoltaic power generation of 20,000 KWH, carbon emissions can be reduced by about 12 tons.
