smartDSS: smart Decision Support System
Solution comprised of: 1) a tool to measure, predict and balance energy production, demand and storage; 2) a tool to measure and verify reductions in energy consumption and GHG Emissions resulting from city energy use; and 3) user-friendly web portals and functions that will inspire new business models for all stakeholders (consumers, prosumers, city authorities, energy service providers, telecommunication companies, ESCOs, etc.). The Decision Support System leverages the cities’ intelligent electrical and thermal grids to empower all of the actors involved and enable optimal distribution and trading of decentralized renewable energies production in a city, as well as the integration of Combined Heat and Power (CHP) plants connected to the smart district heating and cooling grid.

The use of various methods (such as education, financial incentives and other DR instruments) to modify consumer demand for energy.
DG: Distributed Generation
Generation of electricity and heat from dispersed small or medium-sized units and connected to the low voltage and/or district heating & cooling grid. Data from DG systems is sent to the smartDSS via the Energy Routers.
Any number of mechanisms to manage customer consumption of electricity in response to supply conditions, in order to reduce peak situations in the electricity distribution grid.
DS: Distributed Storage
Accumulation of electric energy in dispersed autonomous storage units.
DSO: Distribution System Operator
A stakeholder that manages and operates an energy distribution network and delivers electricity to end-users.
In the context of iURBAN, an endpoint is a device or entity in which energy-related parameters are monitored (i.e. smart street lighting systems, a CHP plant, an electricity meter in a commercial building, an EV charging station, etc.).
An Energy Router refers to a BEMS, Smart Meter or other metering device. In the iURBAN scenarios, each building or end point will collect data related with energy consumptions and productions in which the Energy Router will ensure lossless data communication to the Smart City Database.
EV: Electrical Vehicle
A battery-powered vehicle which uses one or more electric motors for propulsion. In iURBAN both EVs and EV Charging Stations can be considered both as a load (when recharging) or an energy storage unit (when charged).
GUI: Graphical User Interface
A user interface that allows users to interact with electronic devices with images rather than text commands. The iURBAN smartDSS will create two GUIs: a Local Decision Support System (LDSS) and a Centralized Decision Support System (CDSS).
A low-cost embedded device that sends energy information produced by loads, storage and generating units to the smartDSS.
HVAC: Heating, Ventilation and Air Conditioning
Any of a number of devices and systems that produce and/or distribute warm/cool air within a building.
IoT: Internet of Things
IoT refers to a global network infrastructure, linking physical and virtual objects through the exploitation of data capture and communication capabilities.
LDSS: Local Decision Support System
Software designed to engage consumers and prosumers by capturing near real-time data related to their energy consumption, as well as production from their installed Distributed Energy Resources (DER), and display it via the LDSS GUI on smart phones, tablets, PCs, etc.
The Media Access Control Layer is one of two sublayers that make up the Data Link Layer of the OSI model. The MAC layer is responsible for moving data packets to and from one Network Interface Card (NIC) to another across a shared channel.
M2M: Machine to Machine
A communication approach that includes any technology enabling automated wired or wireless exchange of data between devices. Within iURBAN M2M communication approaches and standards are used to support inter-operation of loads, generation and storage units with GWs.
Small-scale versions of the centralized electricity distribution system. In GreenCom it includes local energy generation, energy storage, and loads monitored and controlled by a single MGM through gateways. In GreenCom a set of microgrids are managed by a single MGA that exchanges control signals and information from service provider, with many MGMs.
A ready to use IoT m2m platform that provides: (i) common data base of energy related information and interfaces for the integration of different sources of information from ICT infrastructures in place within iURBAN, (ii) An orchestration engine leveraging control and data to the different processing components, services and devices of the smartDSS (gateways, prediction algorithms, simulation, data fusion, data aggregation, etc.) and (iii) standardized API for 3rd party tools integration.
Open Data API: Application Programming Interface
A set of services exposed by a SW module and documented programmatically in order to enable programmers to access functionalities of the SW module itself without dealing with its internal details. iURBAN develops an open data API to be used both internally (i.e. to simplify extension and maintenance of the iURBAN smartDSS) and externally (i.e. to facilitate access by authorized third-parties).
Components of the ICT infrastructure corresponding to the Hardware.
A device or stakeholder which can act both as an electricity/energy consumer or producer.
Refers to renewable energy installations comprised of photovoltaic cells to directly convert sunlight into electricity. iURBAN primarily considers distributed PV installations, though large-scale deployments (i.e. solar farms) supplying energy to a city will also be taken into account.
RES: Renewable Energy Source
An energy source that produce energy from resources that can be replenished naturally such as sunlight, wind, geothermal heat, rivers, tides, etc.
SOA: Service oriented Architecture
Software that is designed and developed using a set of principles and methodologies that enable interoperable services. These services are well-defined business functionalities that are built as software components (pieces of code and/or data structures) that can be reused for different purposes.
A conceptual entity which is a set of computer programs, procedures, and associated documentation related to the operation of a data processing system.
TSO: Transmission System Operator
An entity responsible for the transportation of energy in the form of electricity or gas on a national or regional level, using a fixed infrastructure. Although the principal objectives of iURBAN do not directly involve the participation of the regional TSOs, the project will consider business models involving the TSO.
VPP: Virtual Power Plant
A VPP refers to a cluster of distributed generation installations (such as solar PV installations, micro-CHP, EV charging stations, wind-turbines, storage devices, etc.), not necessarily confined to a single electricity substation, that are aggregated into one system. In addition, the iURBAN project will develop VPP simulations to understand how non-existing “virtual” units could affect the current energy situation of the city in terms of consumption, production, CO2 emissions, etc.
Wide Area Network
A large-scale communication network spanning long distances (regions, countries) and typically employing broadband wired communication technologies. iURBAN will aim to bridge various Wide Area Network standards to enable manageable communication between devices.
