Changelog

Added

• definition for a default input file directory structure
• tarball utils to extract and compress files
• added electric vehicle charging station implementation EvcsInput
• reading time series from csv files (including a container object to hold the different types of time series)
• reading mapping from participant uuid to time series uuid including a mapping object for easy access to time series
• Couchbase, SQL and CSV connectors and sources for weather data
• added validation utils that can be used to check whether objects have valid values (no usage implemented yet)
• added SystemParticipantWithHeatResult with thermal power variable to be used by heat plant result models

Changed

• BREAKING: replaced Unit API 1.0 (JSR 363, tec.uom.se) with Unit API 2.0 (JSR 385, tech.units.indriya)
• added possibility to allow null values in time series for missing values (e.g. if some measure data points from real world data time series are missing)
• moved api docs to own branch incl. automated api-docs deployment
• added methods for nearest and all coordinates to IdCoordinateSource
• utilize factory in IdCoordinateSource to maintain highest possible flexibility
• added coordinate distance sort method to GridAndGeoUtils
• BREAKING: Harmonized field naming for time information
• BREAKING: Properly applying snake case to result file names
• deprecated TarballUtils
• updated Indriya to version 2.1.2 to include fixes for serialization
• Reworking the time series source (one source per time series, distinct mapping source, factory pattern)
• BREAKING: Moved methods buildSafe{Coord,Point,LineString,LineStringBetweenCoords,LineStringBetweenPoints}, totalLengthOfLineString from GridAndGeoUtils to GeoUtils in PowerSystemUtils
• BREAKING: Moved CoordinateDistance to PowerSystemUtils
• Factory methods for SubGridGate
• BREAKING: Inheritance hierarchy of exceptions all around entity validation

Removed

• BREAKING: Removed deprecated code parts
  • Intermingled builder pattern and constructors in SubGridGate
  • TarballUtils that have been transferred to FileIOUtils in PowerSystemUtils
  • FileNamingStrategy that has been transferred to EntityPersistenceNamingStrategy
  • EvCharacteristicInput and TimeSeriesContainer that shouldn't be used anymore

Fixed

• InfluxDbConnector now keeps session instead of creating a new one each call
  (resolves #247
  and #248)
• BREAKING: fix invalid application of solar irradiance / irradiation (#266)
• BREAKING: deleted IrradiationValue as it is invalid and no longer required
• added copy builder implementations for thermal input models CylindricalStorageInput, ThermalBusInput and ThermalHouseInput
• the sample code for reading and writing model data from respectively to csv files documented in the Sphinx documentation is fixed

Released

2020-09-15

Maven central

https://search.maven.org/artifact/com.github.ie3-institute/PowerSystemDataModel/1.1.0/jar

Changelog

Added

• Headline in csv files is now mandatory. CsvDataSource checks for existing field uuid in first row of .csv file
• Minor logging improvements
• New constructor in Transformer3WInput that allows the internal node to be marked as slack
• Method in ContainerUtils to modify a provided SubGridContainer with slack nodes and make it usable for
  most of the commonly known power flow calculations
• gradle task to create JavaDoc HTML files in the folder 'docs/javadoc'
• added missing HpResult model
• Implementation of DataConnector, WeatherSource and DataSink for InfluxDB
• Introduction of a IdCoordinateSource and implementation of corresponding csv source for ID to coordinate mapping
• Factory for TimeBasedValues<WeatherValue>
• Documentation with Sphinx / ReadTheDocs: https://powersystemdatamodel.readthedocs.io/en/latest/
• Introduction ofSwitchResultFactory to build adapted SwitchResult entities
• Copy method for all RawGridElements and SystemParticipants input entities which allow an easy to use entity copy with altered field values
• distanceBetweenNodes(NodeInput nodeA, NodeInput nodeB) in GridAndGeoUtils
• Additional constructors based on lists of entities in RawGridElements, SystemParticipants and GraphicElements
• Added DistanceWeightedGraph + corresponding utility method to generate a graph topology whose vertices are NodeInput entities and its edges are weighted with the distance between the vertices in meter
• Added ContainerNodeUpdateUtil to support updating nested nodes in GridContainer instances
• Gradle task gradle finalizePR to format and test the code as well as generate JavaDoc

Changed

• Disabled concurrent writing in CsvFileSink.persistJointGrid() as this caused concurrency issues
• Modifications in LineInput and GraphicInput constructors to make LineStrings with two exactly equal
  coordinates or multiple exactly equal coordinates possible
• Extended functionality of GridAndGeoUtils
• CsvFileConnector is now set up to process either UniqueEntities or only by file name
• SwitchResult superclass changed from ConnectorResult to ResultEntity
• CsvDataSource now parses valid RFC 4180 rows correctly (invalid, old syntax is still supported but deprecated!)
• Consolidate test tasks. gradle allTests is now replaced by gradle test. Only unit tests can be run with gradle unitTest.

Fixed

• CsvDataSource now stops trying to get an operator for empty operator uuid field in entities
• CsvDataSource now parsing multiple geoJson strings correctly
