Ankerui Hydroelectric Energy Monitoring System Energy Management

Description :

　　As soon as the electricity sales market opened up, it faced intense competition and relaxed policy restrictions on the entry of electricity sales companies, resulting in a rapid growth in the number of electricity sales companies. As of March 31, 2018, the number of publicly announced electricity sales companies nationwide has increased to 3410. But for power sales companies to survive, it is crucial to acquire more customers. The main factors for acquiring and retaining customers are as follows: 1) reducing purchase electricity prices: having good bargaining power with power generation companies, being able to obtain contracted electricity at a lower cost, and having greater room for concessions to customers, making it more likely to acquire customers. In this regard, power sales companies under power generation companies have a natural advantage; 2) Providing better services: Electricity sales and services are inseparable. If it is impossible to obtain lower electricity prices than competitors, then we can only provide better services to retain customers, including data services, electrical installation and testing, hidden danger investigation, power repair, operation and maintenance, etc., to increase customer stickiness; 3) Reducing operating costs: If the electricity sales company can better control the operating costs of electricity sales than its competitors, there will be more room for customers to make concessions. This requires the use of energy platforms and other tools to help the electricity sales company save labor costs and operate at lower costs. 3. The electricity trading and sales market is still undergoing deepening reforms, and sales companies will be greatly affected by policy changes in the future. With the popularity of electricity trading platforms and various energy data platforms, real-time trading in the rapidly changing electricity market has become possible. On November 8, 2018, the Comprehensive Department of the National Energy Administration issued a notice on improving the pilot mechanism for the construction of the electricity market. The electricity market will be piloted in eight regions including Guangdong, Zhejiang, Shandong, Shanxi, and Fujian. In principle, the pilot simulation and trial operation should be carried out before the end of June 2019. Through centralized competition optimization, time of use node electricity price signals will be formed at different nodes to truly reflect the spatiotemporal value of electricity commodities at different times and locations. Imagine that in the future, electricity prices will fluctuate in real time every day and every hour. If power sales companies do not use energy platforms reasonably and cannot obtain energy data in real time, it will be difficult for them to stand firm in fierce competition

　　With the rise of new energy, how to manage the relationship between the internal load of enterprises and photovoltaic, energy storage, and charging piles, optimize management through statistical analysis of the system, and achieve reliable monitoring of power supply, billing management, energy consumption analysis management, and dynamic area management. Helping customers achieve unified energy management and cost reduction and efficiency improvement is a problem that Tianqi needs to solve.

　　Due to the fact that the electricity volume in medium and long-term trading contracts is predicted, deviation is an inevitable phenomenon. But how to control the deviation of electricity to a lower level is the primary issue that power sales companies need to solve. Whether in the current or future electricity sales market, deviation assessment will be one of the major challenges for electricity sales companies and have a direct impact on their profits.

　　For power sales companies, there are mainly two methods for deviation assessment and control:

　　1) Electricity sales companies need real-time understanding and prediction of user data. By using energy big data platforms and other tools to collect historical data on user electricity consumption behavior and predict the future, we can better manage and avoid individual user deviations to ensure the controllability of overall deviations for power sales companies.

　　2) Adopt appropriate methods with customers, partners, third parties, etc., and share the risk of deviation assessment through methods such as deviation electricity transfer and risk transfer.

　　AcrelCloud-1000 substation operation and maintenance cloud platform provides solutions for the pain points of power sales companies mentioned above.
