Background Introduction
State Grid Henan Electric Power Company maintains the entire Henan power grid with the capacity reaching up to 70 million kW, located at the hub of the national power supply network. In January 2021, Henan Electric Power Company teamed up with Huawei Cloud Stack to build China's first provincial energy big data center providing a wide range of smart solutions to converge huge volumes of energy data and help the government make data-driven decisions.
Goals & Challenges
-
Henan Electric Power Company set the following goals to match China's 30/60 goal to achieve peak emissions by 2030 and hit carbon neutrality by 2060: By 2025 and 2030, in the entire Henan province, non-fossil energy should account for no more than 18% and 25%, respectively, of total primary energy consumption, and the total of both electricity transferred from other provinces and clean electricity should account for 38% and 48% respectively.
There are huge challenges to achieving such goals. Xing Ziya, deputy director of the data office in the Internet department of Henan Electric Power Company, said: "More and more electronic devices are being used, more renewable energy is being used, and there are ever-increasing differences between loads in peak and off-peak hours, which presents new challenges for our traditional power systems."

A Digital Electric Power Platform Built with Huawei Cloud Stack
-
A "One-level Operations + Two-level Maintenance" architecture
With the cloud platform powered by Huawei Cloud Stack, State Grid has built a unified electric power cloud covering its HQ plus 14 provincial subsidiaries. The unified cloud uses a "one-level operations and two-level maintenance" architecture that allows for unified resource monitoring and management. As a provincial subsidiary, Henan Electric Power Company provisions services and manages resources through a central operations platform at the HQ, and uses its own level-2 maintenance system (under the level-1 maintenance system at the HQ) for routine maintenance including alarm management, troubleshooting, and resource scaling, as well as centralized management of diverse clouds and virtual resource pools.

Enabling data sharing and maximizing data value
Huawei Cloud Stack's Data Lake Governance Center (DGC) provides Henan Electric Power Company with a way to streamline data ingestion, conversion, and consolidation. It breaks down barriers to data sharing, enriches data models, and continuously improves data quality; it unifies data standards and standardizes interface calls, achieving Data as a Service (DaaS); it strengthens the data O&M and related systems, supporting the application of multi-dimensional lean management; it supports unified buildout of information systems and development of digital products, promotes the adoption of big data applications, and provides analytical services, powering data operations.
Based on Huawei Cloud Stack, the energy big data center of the Henan province converges huge volumes of data from every relevant sector across the entire province, covering 626 major energy companies, 32,000 public charging piles, and 43 million consumers.

A clean heating platform using electricity and gas instead of coal has been developed for the government as well as power and gas suppliers to keep abreast of project progress and monitor heating status. This platform is now used by more than 6 million consumers throughout the province.

A new power-balance model was precisely calculated for the first time, with large-scale integration of renewables, including wind and solar, into the power greatly reducing reliance on gas and coal based power sources.
Big data analysis was performed, combining the real-time output of renewable power stations and local weather forecasts with historical records in the Henan province. The analysis results helped improve photovoltaic output certainty by 15%, and that of wind power by 10%. The contribution of renewable energy power is expected to increase capacity by 2.5 million kW in peak hours, which will reduce the required spend on new power grid investments by CNY15 billion.

A smart charging application connected to 31,200 charging piles in 851 charging stations across the province has been launched. It allows users to apply and receive approval for charging subsidies entirely online.
