Recently, the Comprehensive Department of the National Energy Administration issued a notice on strengthening the management of user side network security (hereinafter referred to as the "Notice"), which systematically constructs the top-level design and full chain management system of user side network security management at the national level. The "Notice" points out the overall requirements for user side network security management, clarifies the scope of responsibilities of each relevant entity, and promotes the institutionalization, collaboration, and refinement of user side network security management.

In this context, Shenzhen Zhongdian Electric Power Technology Co., Ltd. (referred to as "CET") provides products and solutions for the safe and stable operation of new power systems with its profound accumulation and innovative technologies in the fields of electric energy management and energy management, achieving "prevention first, source prevention and control".

1、 Power Security Challenges in the New Power System

The Notice strengthens control from the source, strengthens the first line of defense, aims to improve the power safety supervision system, and promote key work in power safety supervision. At present, the new power system pursues "source grid load storage" collaborative interaction, and safety is the prerequisite for achieving interaction.

Among them, the Notice requires user side devices to be connected to the scheduling system to achieve "observability, measurability, adjustability, and controllability". This is not only a requirement for security control, but also the foundation for user participation in demand response, virtual power plants, and other new formats.

In addition, with the integration of a large number of power electronic devices, new energy generation equipment, and electric vehicle charging facilities, power quality problems such as harmonics, voltage fluctuations, flicker, and three-phase imbalance in the power grid are becoming increasingly prominent.

The upgrade of user side safety management from the "end management" of traditional power grids to the "end governance" of new power systems reflects the deep logic of energy transformation: safety and development have never been in opposition, but a mutually supportive unity.

2、 Introduction to the Advantages and Solutions of CET Technology

Faced with the many challenges of the new power system, Shenzhen Zhongdian Power Technology Co., Ltd. (referred to as "CET Zhongdian Technology") has provided a series of innovative products and solutions with its comprehensive strength in power secondary equipment, power management software, and system integration, to safeguard the safety level and power quality of the power system.

In response to the power quality issues faced by the new power system, CET China Electric Technology has a deep technical accumulation in the field of power quality. Its smart meters and power quality monitoring devices, such as the iMeter series, can monitor and analyze power quality indicators such as harmonics, voltage deviations, three-phase imbalances, voltage fluctuations, and flicker in the power grid in real-time and with high precision. Compliant with international standards such as IEC61000-4-30, it provides users with comprehensive and accurate power quality monitoring data, providing an important foundation for evaluating power quality status and formulating governance plans.

In response to the notice's emphasis on enhancing the "four capabilities" of photovoltaics, CET China Electric Power Technology has launched a distributed photovoltaic grid connected solution for industrial and commercial use. The data collection and upload of inverters' voltage, current, power generation, power factor, etc. to the cloud, through flexible regulation, on-site monitoring, and cloud operation and maintenance, realize the full life cycle operation and maintenance management of distributed photovoltaics, respond to the observability and measurability of distributed photovoltaic data, and enable adjustable and controllable power generation, providing strong support for the construction of new power systems.
