Understanding Dynamic Operating Envelopes

Dynamic Operating Envelopes (DOEs) adjust import and export limits over time and by location, according to the available capacity of the local network or the power system as a whole.

A DOE refers to the grid-safe technical limit that defines the permissible import and export levels for Distributed Energy Resources (DERs) at each connection point. This is also known as the Technical Operating Envelope (TOE).

The Dynamic Operating Envelope (DOE) serves as a constraint for DERs that must be respected when optimizing their operation to achieve various objectives. These limits are applied as constraints in any DER optimization process.

For Behind-the-Meter (BTM) DERs, DOE limits enable the export of energy to the grid within dynamically determined boundaries. These limits can be communicated to Edge DERMS or aggregators, who in turn can pass them on to BTM DERs. For third-party DERs, the limits may also be shared directly with the DER owner if they choose to participate in the market.

Data Requirements for Dynamic Operating Envelopes

To enable Dynamic Operating Envelopes (DOEs) analysis, the following data configuration is required:

1. Only DER units with a positive MAX_ENERGY in PF_DIST_GEN table will be considered.

2. SRS rule category Advanced ADMS Options should have a rule:

• RULE VALUE 1: useEnergyStorageDevices

• RULE VALUE 2: 1

• RULESET: Power Flow

• INCIDENT TYPE: Any

3. Define the schedule time, analysis start time, number of analysis intervals, and the time between analysis intervals in the Dynamic Operating Envelopes (DYNAMIC_OPERATING_ENVELOPES) SRS rule.

4. Need to define bids in the DERMS_BID table.
