The SEAS Trading ontology Gabriel Santos v1.1 seas 2016-11-15 Antoine Zimmermann Erkki Siira The Seas Trading Ontology defines concepts and relations to describe ownership, trading, bilateral contracts and market licenses: - players own systems and trade commodities, which have a price; - bilateral electricity contracts are connections between electricity traders at which they exchange electricity; - electricity markets are connections between electricity traders at which they exchange electricity, using a market license; - electricity markets can be cleared, and balanced; - evaluations can have a traded volume validity context 2016-11-15 testing Negative Load Shifting is a Load Shifting which occurs when the load is less than the initial request. Negative Load Shifting testing Ancillary services are the specialty services and functions provided by the electric grid that facilitate and support the continuous flow of electricity so that supply will continually meet demand (source: Wikipedia). These include black start capability (the ability to restart a grid following a blackout); frequency response (to maintain system frequency with automatic and very fast responses); fast reserve (which can provide additional energy when needed); the provision of reactive power and various other services. (source: Entso-e) Ancillary Service testing The execution of some balancing procedure on a market. Balancing Execution testing The execution of some Negative Load Shifting procedure on a market. Negative Load Shifting Execution testing In economics, market clearing is the procedure by which, in an economic market, the supply of whatever is traded is equated to the demand, so that there is no leftover supply or demand (source: Wikipedia). Clearing testing In economics, a commodity is a marketable item produced to satisfy wants or needs. Often the item is fungible. Economic commodities comprise goods and services (source: Wikipedia). For instance, the electric energy outgoing of a certain connection point can be a commodity, and have a price: ``` [] seas:outgoingElectricEnergy [ a seas:ElectricEnergyProperty ; seas:price [ a seas:Price ; seas:evaluation [ a seas:Evaluation ; seas:evaluatedValue "200 €"^^xsd:ucum ; seas:hasTradedVolumeContext "12 €/MWh"^^xsd:ucum ] ] ] ``` Commodity testing An Electricity Market License is a connection point between a player and a market. Electricity Market License testing An electricity bilateral contract is both a connection between electricity players, and a contract. It only connects electricity traders. It is linked to some player that validates each trade. Electricity Bilateral Contract testing Load Shifting is the procedure of balancing the supply of electricity on the network with the electrical load by adjusting or controlling the load rather than the power station output. (source:Wikipedia) . Load Shifting testing Positive Load Shifting is a Load Shifting which occurs when the load is greater than the initial request. Positive Load Shifting testing The execution of some Load Shifting procedure on a market. Load Shifting Execution testing In economics, a service is an economic activity where an immaterial exchange of value occurs. When a service such as labor is performed the buyer does not take exclusive ownership of that which is purchased, unless agreed upon by buyer and seller. The benefits of such a service, if priced, are held to be self-evident in the buyer's willingness to pay for it (source: Wikipedia). Service testing The execution of some Positive Load Shifting procedure on a market. Positive Load Shifting Execution testing In economics, a good is a material that satisfies human wants and provides utility, for example, to a consumer making a purchase while getting an enough-satisfying product. A common distinction is made between 'goods' that are tangible property, and services, which are non-physical (source: Wikipedia). Good testing A procedure executed by some player. The execution of some clearing procedure on an electricity market. Clearing Execution testing Balancing refers to the procedure in which a Balance responsible party acts to ensure that demand is equal to supply after markets have closed, in and near real time (source: Entso-e). Balancing testing Tax for the commodity, quantified as a percentage of something. Functional sub properties of `seas:tax` must precise what that _something_ is. tax testing Links some connection to a player that regulates what's happening through that connection. operated by testing Links an electricity player to its electricity market license. has electricity market license testing An Electricity Player can trade electricity on an Electricity Market. For example, ``` <http://market.com/> a seas:ElectricityMarket . <http://agregator.com> a seas:ElectricityTrader ; seas:tradesElectricityOn <http://market.com/> . <http://otheragregator.com> a seas:ElectricityTrader ; seas:tradesElectricityOn <http://market.com/> . ``` These connections are qualified with class `seas:ElectricityMarketLicense`. For example, ``` <http://agregator.com> seas:hasElectricityMarketLicense <http://market.com/license12> . <http://otheragregator.com> seas:hasElectricityMarketLicense <http://market.com/license32> . <http://market.com/> seas:connectsSystem <http://agregator.com> , <http://otheragregator.com> . <http://market.com/> seas:connectsSystemAt <http://market.com/license12> , <http://market.com/license32> . ``` trades electricity on testing An Electricity Player can trade electricity directly with another electricity player, through an electricity bilateral contract. They then exchange some of the commodities they trade. These connections are qualified with class `seas:ElectricityBilateralContract`. trades electricity with testing Links a system to the one and only player that owns it. is owned by testing Links an evaluation to its traded volume validity context. for instance . ``` <myConnectionPoint> seas:outgoingElectricEnergy <whatIGive> . <whatIGive> seas:price <priceOfWhatIGive> . <priceOfWhatIGive> seas:evaluation <evaluationOfThePriceOfWhatIGive> . <evaluationOfThePriceOfWhatIGive> a seas:Evaluation ; seas:evaluatedValue "200 €"^^cdt:ucum ; seas:hasTradedVolumeContext "12 €/MWh"^^cdt:ucum . ``` This concept needs polishing ... please ping me if necessary. has traded volume context testing A value-added tax (VAT), known in some countries as a goods and services tax (GST), is a type of general consumption tax that is collected incrementally, based on the value added, at each stage of production and is usually implemented as a destination-based tax, where the tax rate is based on the location of the customer (source: Wikipedia). The value added tax is quantified as a percentage of the nett price. value added tax testing Links a commodity to the one and only player that trades it. is traded by testing Links a player to a system it owns. owns testing Links a player to a commodity it trades. trades
