Smart Grid upgrades distribution network and power management

Speaking of distribution network intelligence, many people will think of distribution automation. Distribution network automation is also an important part of smart distribution network, but it only achieves some functions such as improving the reliability of power supply and shortening the power outage time. The smart distribution network is an organic integration of multiple information and functional modules.

The so-called organic integration, that is, through cross-platform data / information management, to achieve more and more advanced applications. It further emphasizes the improvement of the entire distribution network's operation level. For example, how to fill the valley through peak load shifting and effectively transfer the load on the basis of existing grids to deliver more electricity, instead of simply increasing the capital investment; how to pass through the entire network? Power/voltage management to reduce line losses; how to link real-time load forecasting with meteorological and distributed energy sources, combine with time-of-use electricity prices, guide customer spending, and fully increase the average hourly utilization of existing generator sets, instead of simply adding new units To meet the unplanned peak demand; how to improve the power grid's own crisis management capabilities, so that it has early warning, rapid judgment, self-recovery and Other "self-healing" function. Smart distribution networks can also help improve the efficiency of production dispatchers through advanced grid rapid simulation, many visual tools, and intelligent expert systems.

Many U.S. power companies have installed smart energy meters and advanced metering systems as an important part of building a smart grid. As a real-time interactive tool between power customers and power companies, smart power meters have two major functions: First, they are information and control terminals that fulfill demand response; Second, they are functional modules such as power outage management and power quality management. The source of information, it will be the fault location of the entire distribution system and power monitoring into the power supply end. Coupled with integrated geographic information systems and expert systems, power companies can more intuitively and quickly handle various incidents and conditions, greatly improving operational efficiency.
