The "14th Five-Year Plan for Modern Energy System" proposes to innovate the structural form and operation mode of the power grid and accelerate the construction of a modern energy system. Speed up the transformation and upgrading of distribution network, promote the construction of intelligent distribution network, and improve the carrying capacity and flexibility of distribution network to accept new energy and diversified loads. Actively develop smart micro-grids that mainly consume new energy to achieve compatibility and complementarity with large power grids.
At the United Nations Climate Summit in 2020, my country officially proposed the "3060" dual carbon goal. In order to achieve the goal of "carbon peaking by 2030 and carbon neutrality by 2060", we will strive to build a clean, low-carbon, safe and efficient energy system, improve the level of clean energy utilization and the operation efficiency of the power system, and better utilize the load on the source network The role of storage integration and multi-energy complementarity in ensuring energy security.
Under the new power system, the operation of the power grid gradually presents the characteristics of intelligence and digitization. The development of "source-network-load-storage integration" operation urgently requires cloud computing, big data, power Internet of Things, edge computing and other technical means of "cloud, big data, power Internet of things, edge computing", so that the power grid system is equipped with massive data processing and analysis, highly intelligent Cloud solutions for decision-making and other capabilities. In order to realize the integration of various energy resources, break through the barriers between multiple energy links, and make the elements of "source, network, load and storage" truly achieve friendly coordination.
Technology promotes new energy power generation and micro grid technology, and effectively realizes the integrated management and control of source, network, load and storage.
Relying on new technologies such as modern information communication, big data, artificial intelligence, energy storage, etc., and using the new model of "Internet +", the load-side adjustment and response capabilities are mobilized. In urban commercial areas, complexes, and residential areas, relying on photovoltaic power generation, grid-connected microgrids, and charging infrastructure, etc., develop park (residential) level that combines distributed power generation and flexible charging and discharging of electric vehicles (user energy storage). Source-network-load-storage integration construction. In areas with large industrial loads and good new energy conditions, support the development and construction of distributed power sources and nearby access and consumption, and carry out green power supply construction integrating source, network, load and storage in combination with incremental power distribution networks and other work.
Tupu software digitally twins the web smart "dual carbon" microgrid scenario. The overall scenario adopts a lightweight modeling method, focusing on the equipment and buildings in the four aspects of source, network, load, and storage in the power grid connection of the smart park. Modeling is restored to bring users a "cyberpunk" visual experience.
Supports 360-degree observation of the dynamic data of each link of the source network, load and storage in the virtual park. Through the built-in interaction of the Tupu software HT, you can realize the mouse rotation, translation, zoom in and zoom out operations, and also realize the touch screen device. One-finger rotation, two-finger zoom, and three-finger pan operations no longer have to worry about different interaction modes across platforms.
"Integration of source, network, load and storage" is an operation mode and technology that can maximize the utilization of energy resources. Economically, efficiently and safely improve the power dynamic balance capability of the power system.
Different power sources can be effectively coordinated through the "source, network, load and storage integration" platform, that is, through the coordination and complementation between flexible power generation resources and clean energy, to solve the randomness and fluctuation of clean energy power generation output due to environmental and meteorological factors. It can effectively improve the utilization efficiency of renewable energy, reduce the rotating reserve of the power grid, and enhance the self-regulation ability of the system.
Using the graphical configuration SCADA capability provided by HT, the entire process of photovoltaic conversion from light energy to electric energy, to equipment power supply, and energy storage is expressed in the form of line flow. Excessive power consumption, cumulative power consumption, illumination duration, and irradiance are counted separately on that day, which is conducive to integrated analysis. Use the bar chart to dynamically display the AC source output and commands within 24 hours, grasp the daily data changes, and improve the power control ability.
As a micro integrated energy system close to the user side, the microgrid covers primary energy such as solar energy, wind energy, and secondary energy of electricity, and involves multiple energy transmission and distribution networks of electricity, heat, and gas, as well as load demand, energy storage, control and protection equipment. and information platform, it is necessary to take electric energy as the core, through multi-energy interconnection, information energy coupling and market economy guidance, to achieve multi-energy "supply-demand-storage" coordination optimization and self-balancing.
