Smart Grid Architecture Model Sample Clauses

Smart Grid Architecture Model. The SEGRID architecture is based on the Smart Grid Architecture Model (SGAM) developed by the Smart Grid Coordination Group (SG-CG) formed by the European standardization organizations CEN, CENELEC, and ETSI [16], [17], [18], [19]. As depicted in Figure 4, the SGAM framework is three-dimensional involving domains, zones, and interoperability layers. The domain of energy distribution is the centre of the SEGRID use cases. The logically connected domains in SEGRID involve transmission, producers of distributed energy resources (DERs), and consumers ranging from large factories to standard private households. To establish a hierarchy on the smart-grid plane, SEGRID security solutions are devised per zone: the process, field, station, operation, enterprise, and market. As a reminder, Table 1 lists the definitions of each zone from the SGAM Reference Architecture. Process Including the physical, chemical or spatial transformations of energy (electricity, solar, heat, water, wind …) and the physical equipment directly involved. (e.g. generators, transformers, circuit breakers, overhead lines, cables, electrical loads any kind of sensors and actuators which are part or directly connected to the process,…). Field Including equipment to protect, control and monitor the process of the power system, e.g. protection relays, bay controller, any kind of intelligent electronic devices which acquire and use process data from the power system. Station Representing the areal aggregation level for field level, e.g. for data concentration, functional aggregation, substation automation, local SCADA systems, plant supervision… Operation Hosting power system control operation in the respective domain, e.g. distribution management systems (DMS), energy management systems (EMS) in generation and transmission systems, microgrid management systems, virtual power plant management systems (aggregating several DER), electric vehicle (EV) fleet charging management systems. Enterprise Includes commercial and organizational processes, services and infrastructures for enterprises (utilities, service providers, energy traders …), e.g. asset management, logistics, work force management, staff training, customer relation management, billing and procurement… Market Reflecting the market operations possible along the energy conversion chain, e.g. energy trading, mass market, retail market. Security is defined with respect to the third dimension in the SGAM, the five interoperability layers. Use...
