Abstract: the microelectronic controller is responsible for the operation of the whole system. This coordination layer manages local power generation and storage functions, load management and power services to achieve expected goals related to energy costs, carbon dioxide emissions and reliability

recently, the national development and Reform Commission and the National Energy Administration issued the Trial Measures for promoting the construction of parallel micro electricity (hereinafter referred to as the measures), which aims to promote the reform of the energy supply side, promote and regulate the healthy development of micro electricity, guide the local consumption of distributed energy and renewable energy, and establish an energy production and consumption system with diversified integration, supply and demand interaction, and efficient allocation. A series of factors, such as its unique advantages, the development of innovative technologies, and favorable policies, are creating opportunities for its development, or will usher in a new explosion point

the deployment of micro power emphasizes the application of new technologies, enables distributed energy to collaborate around common goals, helps operators formulate analysis strategies that can optimize the operation and management of interconnected systems, and alleviates the design limitations of two-way power systems. Schneider Electric, an expert in the field of global energy efficiency management and automation, as a pioneer in the field of micro electricity, pays attention to the way in which micro electricity technology can achieve the best cooperation in distributed energy, and strives to maximize the benefits of micro electricity through innovative practices

advantages of micro electricity

in Schneider Electric's view, micro electricity has outstanding advantages in four aspects: energy reliability, easy access to energy, energy independence and energy cost optimization. Firstly, the micro detection method includes water leakage experiment. The electricity can be independent of the main electricity to achieve self-sufficiency, thereby improving the elasticity of power supply. When the main power encounters major problems, the micro power can be quickly decoupled and can still continue to supply power from the local power supply. In addition, when the risk is predictable, we can prepare for wechat by deliberately adopting preventive strategies. When there is a problem with wechat itself, wechat can back up and automatically reconfigure

in terms of energy access, micro electricity can speed up the deployment of smart electricity and increase the opportunities for people in developing countries to access energy; It can also reduce fossil fuel consumption by integrating more renewable power generation methods, which is conducive to the realization of "energy independence". In addition, wechat can use energy flexibility to optimize energy structure and electricity balance, and optimize energy costs. One of its goals is to achieve the self-sufficiency consumption of local renewable green energy, so that it can partially or completely replace the energy provided by main electricity, thus helping to reduce energy-related greenhouse gas emissions. Another goal is to use on-site distributed generation as a flexible energy resource to optimize the participation of demand response procedures

micro electric technology innovation and optimization

in terms of deployment, micro electric aims to meet the expectations of global energy transformation such as economy, low carbon and security through efficient distributed energy integration and flexible control based on its advantages. In order to meet these performance goals, micro electric technology needs to seek optimization and innovation in system control and protection, distributed energy management and energy control around the following aspects:

(I) ensure safe and reliable operation

in micro electricity, the ability of local distributed generation and operation away from the main power island brings new challenges to the design of protection system. With the change of micro electric operating conditions, the network topology also changes. Therefore, the magnitude and direction of short-circuit current capacity may be different. The protection system must be carefully designed to ensure the safety of personnel and equipment in all possible faults in each operation mode, and at the same time, avoid the evaluation work due to wrong protection identification, which is detailed and implemented to the operation team, machine and specific operators, resulting in downtime. In addition to the design of protection system, the measurement of power quality is more important in micro power applications. Specific power quality problems such as harmonics, frequency variation, measurement accuracy, transients, voltage dips and surges should be monitored and analyzed, and kept within the normal operation range

(II) control of distributed energy

(III) optimize energy control

the micro electric controller is responsible for the operation of the whole system. This coordination layer manages local power generation and storage functions, load management and power services to achieve expected goals related to energy costs, carbon dioxide emissions and reliability. The efficient operation of the micro electric controller can be achieved through the following technical solutions: first, the most direct solution is to use the central controller to collect operation information, interact directly with SCADA or cloud services, run optimization algorithms, and deploy the selected strategies to different interconnected assets; The second solution is to realize distributed micro electric controller. This means that each component participates in system optimization and works directly with its peers. In addition, operators can also integrate the above two solutions. For example, in the case of multi facility micro electricity, combining the single facility micro electricity controller (centralized operation) with the distributed method of multi facility micro electricity system coordination will achieve good results

ecostruxure electricity architecture based on IOT: grasp the opportunity of micro electricity outbreak

in the past decade, the substantial progress in the field of distributed energy such as solar power generation and energy storage, as well as the IOT environment have created new collaboration and optimization capabilities for the development of micro electricity. Micro power is becoming a catalyst to promote energy transformation, and is expected to usher in new growth with policy support. In China, micro power is entering a new growth period, and increasingly becomes the way for more and more market players to enter the power world. Schneider Electric provides a complete combination of innovative technologies from interconnected products and edge control to application, analysis and service by clicking the power start button uxure (i.e. ecostruxure grid) architecture on the control panel based on ecostr2 of IOT, and helps new entrants grasp the opportunities of micro electricity in combination with rich global application experience

because most renewable energy sources are intermittent, and micro electricity needs to optimize various energy access and balance power generation and consumption, these two applications need the powerful interconnection performance, IOT technology and computing analysis capabilities provided by ecostruxure electricity. Under the digital electricity architecture, ecostrxure electricity collects and manages key data and obtains rich insights from data analysis to achieve a higher level of asset management, optimize operations and enhance flexibility. Based on ecostruxure power, Schneider Electric combines customized solutions, flexible methods and professional skills, delivers advanced micro power, ensures power independence without affecting the owner, helps users maximize operation time, and obtains the same energy efficiency management capabilities as previous large power production enterprises and distribution enterprises. In the golden development cycle of wechat, this will bring new competitiveness to wechat stakeholders such as power companies, operators and energy users
