Polaris Smart Grid Online News: The gradual shift from coal-based and oil-based sustainable energy supply systems based on renewable energy will be one of the major changes in human development in the 21st century. As the main means of renewable energy conversion and utilization, clean, efficient, and convenient energy consumption forms, electricity will occupy a central position in energy supply and use. This places urgent demands on the continuous improvement of the intellectualization level of the power system.
The intelligent power system integrates advanced sensing measurement, information and communication, automatic control, new materials, and advanced energy storage technologies. It is highly integrated with the infrastructure of the power system for transmission, distribution, and scheduling. Process, full-featured intelligent monitoring, diagnostics, communication, control, decision-making and self-healing capabilities, can carry large-scale renewable energy generation and distributed energy generation to access the Internet, has multiple indicators of self-optimizing operational capabilities, highly informatized, automated, Interactive new modern power system.
Basic features of smart power system
The features of the smart power system include: reliable self-healing, flexible interaction, clean green, quality and efficiency, information integration, and asset optimization.
Reliable self-healing. Self-healing is a significant feature of smart power systems and an essential requirement for their reliability. Reliable self-healing requires the smart power system to predict potential problems on the power grid through on-line self-assessment and to isolate the faulty components from the system with little or no human intervention so that the power grid can quickly return to normal operation and achieve user-friendliness. Uninterrupted power supply service.
Flexible interaction. On the one hand, the smart power system can flexibly support large-scale access of new users such as renewable energy, distributed generation, microgrids, and electric vehicles; on the other hand, the smart power system can realize grid operation and power market, and electricity trading without Jointly connected to promote the implementation of measures such as load side management and user energy efficiency management, and promote the optimal allocation of power resources.
Clean green. The intelligent power system can promote the development and utilization of renewable energy, increase the proportion of clean energy in terminal energy consumption, reduce energy consumption, greatly reduce the negative impact on the environment, and promote clean green development of electricity.
High quality and efficiency. Intelligent power systems can provide different levels of power quality at different price levels to meet user-differentiated requirements; reduce the use of lightning, switching surges, and harmonic sources by applying superconducting materials, energy storage, and power electronics that improve power quality Such disturbances; through the monitoring and implementation of relevant standards, limiting the user load generated harmonic current into the power system. Through real-time monitoring of the operating status of the system, and better regulation of all aspects of transmission, distribution and distribution, energy losses in transmission can be effectively reduced, and power plants can be efficiently generated.
Information integration. Including monitoring, control, maintenance, energy management, distribution management, market operations, ERP, and other types of integrated integration between various information systems, and require the integration of services on this basis. Through continuous process optimization and information integration, the integration of power grid enterprise management, production management, dispatch automation, and power market management business is achieved. A comprehensive supportive decision support system is formed to support the standardization and leanization of business management, and continuously improve the management of power companies. effectiveness. Support the effective development of the electricity market and power trading, achieve rational allocation of resources, reduce power grid losses, and increase energy efficiency.
Asset optimization. The power system is a huge system of high-tech and asset-intensive, with a wide range of equipment and a huge number. Intelligent power system realizes on-line status monitoring of running equipment through high-speed communication network to obtain the running status of the equipment, achieves conditional overhaul of equipment, and at the same time makes the equipment operate in the best state; by adjusting the control device of the system to reduce the loss and eliminate the obstruction. State, select the minimum cost of energy delivery system, improve the efficiency of the operation; through advanced information technology can provide a large amount of data and information, and can be integrated into the existing enterprise system, the system operation and maintenance costs and power grid construction investment Get effective management.
The development goal of intelligent power system
The key technologies of intelligent power systems can be divided into the following three levels:
The first level: The system is a new technology and intelligent power generation, electricity basic technology, including renewable energy power generation technology, UHV technology, intelligent power transmission and distribution equipment, large-capacity energy storage, electric vehicles and intelligent electricity technology and products, etc. .
The second level: system secondary new technologies, including advanced sensing, measurement, communication technology, protection and automation technologies.
The third level: power system dispatch, control and management technologies, including advanced information acquisition and processing technologies, advanced system control technologies, and new system operation and management technologies that adapt to the electricity market and two-way interaction.
The highest form of intelligent power system development is the ability to have multiple indicators and self-optimizing operation, and it is also the long-term goal of smart power systems.
Multiple indicators refer to indicators that characterize the characteristics of smart power systems such as security, cleanliness, economy, efficiency, compatibility, self-healing, and interaction.
Self-optimization refers to the realization of accurate self-state recognition through comprehensive self-monitoring and information sharing based on rational planning and construction, relying on improved and unified infrastructure and advanced sensing, information, and control technologies. Through intelligent analysis to form decision-making and comprehensive regulation, the power system automatically automates the trend of multi-index optimization.
