Knowra Smart grid Smart grid An electricity network that uses digital communication, monitoring, and control to coordinate power generation, distribution, and consumption. It enables two-way information flows alongside electricity flows.
Advanced metering infrastructure : A network of smart meters, communications systems, and data-management tools for measuring electricity use. Smart meters provide granular consumption data and two-way communication between utilities and customers.
Electric power system : The interconnected infrastructure that generates, transmits, distributes, and uses electrical energy. The smart grid is a digitally coordinated form of this broader system.
Microgrid : A group of interconnected loads and distributed energy resources that can operate as a single controllable system. A microgrid can coordinate local generation, storage, and demand, sometimes operating independently of the wider grid.
Conventional power grid : An electricity network operated with comparatively limited digital communication and automated coordination. It provides the traditional baseline against which smart-grid capabilities are often described.
Electricity market : A system of rules and transactions for buying and selling electrical energy and related services. Smart-grid data and flexible resources can alter how market services are measured and provided.
Phasor measurement unit : A device that measures synchronized voltage and current phasors across an electric power system. Synchronized measurements help operators detect disturbances across widely separated parts of the grid.
Electric power transmission : The bulk transfer of electricity over high-voltage networks from generators toward distribution systems. Transmission networks connect large generators, regions, and urban demand centers.
Electric vehicle charging : The transfer of electrical energy from charging equipment to an electric vehicle's battery. Managed charging can shift vehicle demand to periods with available capacity or low-cost electricity.
Energy Internet : A proposed energy system that applies internet-like coordination and exchange to distributed energy resources. The term emphasizes open, distributed energy exchange, while smart grid covers a broader range of modernization.
Renewable energy curtailment : The intentional reduction of available renewable electricity generation, often because the grid cannot use or transport it. Better coordination may reduce some curtailment, but cannot eliminate network and balancing constraints.
