It serves as the foundational asset for collecting, organizing, analyzing, and visualizing operational and performance data. Each PCS asset is uniquely identified and associated with a parent site (e.g., an “Energy Storage Site”), optional PCS station, MV transformer, and/or substation, forming part of the broader asset hierarchy of a **Energy Storage System (ESS)**. ### Functional Description A PCS converts electrical energy between AC and DC forms, enabling bidirectional power flow between the grid and the battery system. It typically includes inverters, rectifiers, transformers, and control systems to manage energy conversion, grid compliance, and operational safety. The PCS is the primary **AC/DC Power Conversion** asset in a battery energy storage plant (see [Domain Categories](/product/docs/domain-categories) for a broader description of other AC/DC Power Conversion assets across different power plants). ## Core Data Model While PCS configurations may vary by vendor and site, Bazefield offers a pre-installed *CORE* data model to account for the most common points, events, and attributes relevant to all PCS units. Model-specific variations are handled through smart [Model Inheritance](/product/docs/asset-model). Vendor-specific points, calculations, and events are packaged in separate asset model templates and are not described here. ![](https://cdn.document360.io/a0786c0f-b171-4b24-8860-c32eb7ef2738/Images/Documentation/image-1754399105854.png?sv=2026-02-06&spr=https&st=2026-11-06T20%3A45%3A46Z&se=2026-11-06T21%3A45%3A46Z&sr=c&sp=r&sig=OOIo95tEGzTuQPC6F8dMq%2F2rIXmK3tNFnVUTQoRB52M%3D) Example of a common Modelling Strategy to encompass variations of data between PCS manufacturers and site-specific SCADA configurations. ### Core Attributes Attributes are fixed key-value pairs used to represent non-time series data associated with each asset (read more about [Attributes](/product/docs/attributes)). While attribute values can differ from asset to asset, critical shared (e.g., *CORE*) attributes defining a PCS asset type, pre-installed in Bazefield, are described below. These are often prerequisite data required for Bazefield applications to function fully. Required for basic Bazefield Core functionality Optional attributes for common additional modelling *Depending on your version of Bazefield, there may be additional advanced attributes not listed here to support data integrations or migrations with other systems.* | Name | Key | Description | Default Value | | | --- | --- | --- | --- | --- | | Latitude | latitude | GPS coordinates for the PCS using WGS 84 system in decimals | - | | | Longitude | longitude | GPS coordinates for the PCS using WGS 84 system in decimals | - | | | Time Zone | timeZone | Local time zone where the PCS is located | - | | | Rated Active Power | ratedActivePower | Maximum AC power output of the PCS in kW | - | | | Rated Reactive Power | ratedReactivePower | Maximum AC reactive power output of the PCS in kVAr | - | | | Discharge Rate | dischargeRate | Nominal discharge rate of the PCS | - | | | Maximum Energy Capacity (kWh) | energyCapacity | Nameplate maximum Energy Capacity (kWh) | - | | | Fully Charged Threshold (%) | fullyChargedThreshold | SOC threshold for the PCS to be considered fully charged (e.g., 95% or greater is fully charged) | 95 | | | Fully Discharged Threshold (%) | fullyDischargedThreshold | SOC threshold for the PCS to be considered fully discharged (e.g., 5% or less is fully discharged) | 5 | | | Charging Threshold (kW) | chargingThreshold | Power threshold for the PCS to be considered Charging and not idle, e.g., -50 = PCS considered charging when output is less than -50kW.
