IBR Event Evidence Readiness Checker

Public client-only planning tool for inverter-based resource event evidence readiness for utility, TSO, DSO, generation, renewable owner, and reliability teams.

Client-only. No uploads, cookies, analytics, or server submission.

Event evidence inputs

Use generic ranges only. Do not enter plant names, asset IDs, customer data, model files, protection settings, or live operating details.

Resource context Exploratory IBR event review Generation or renewable owner team Utility, TSO, DSO, or reliability team Cross-functional utility and owner review Event evidence source maturity Scattered notes and manual exports Known sources with partial exports Aligned evidence package with owners and timestamps Disturbance/event urgency Retrospective learning or low urgency Active follow-up or stakeholder questions Near-term reliability, customer, or regulator response Model/change-log maturity Model version or change log unknown Latest model or firmware context known Model versions, settings changes, and logs are reviewable

Event timestamp alignment Plant, relay, PMU, SCADA, inverter, and operator records can be compared with known time zones and clock sources. PMU, relay, and event records Disturbance records, relay targets, event reports, PMU traces, or sequence-of-event exports are available for review. Inverter/controller logs Inverter, plant controller, PPC, BESS, or OEM logs can be reviewed without exposing live control access. Plant/customer contact path The team knows who can confirm plant status, operator notes, OEM context, or customer-side event observations. Model/version records IBR model versions, parameter sets, firmware notes, or approved study-model references are known. Commissioning/test records Commissioning, performance, ride-through, plant acceptance, or validation records can be linked to the event scope. Protection settings evidence as read-only context Protection setting records or summaries are available only as evidence context, not as an approval workflow. Power-quality/oscillation notes Voltage, frequency, harmonics, flicker, oscillation, or control-interaction observations are captured. Disturbance timeline A reviewable timeline exists for pre-event state, trigger window, device responses, notifications, and closeout. Source provenance Sources, authors, systems, export dates, versions, redactions, and chain-of-custody notes are traceable. Reviewer authority Qualified operations, planning, protection, reliability, owner, or engineering reviewers are named for signoff. Escalation/legal/compliance boundary The team knows when evidence questions must stop and route to compliance, legal, reliability, or formal investigation owners.

IBR event evidence comparison

Event source	Evidence needed	Agentic AI assist	Human approval boundary
PMU, relay, SCADA, or event records	Time-aligned event files, targets, alarms, sequence markers, export dates, and source owners.	Assemble a disturbance timeline, identify gaps, and draft reviewer questions with source references.	Operations, protection, reliability, or engineering reviewers accept the timeline and any escalations.
Inverter, plant controller, or OEM logs	Read-only logs, controller status, firmware context, model/version references, and plant/customer notes.	Organize log evidence, compare timestamps, and summarize candidate questions for qualified reviewers.	Owner, OEM, generation, or utility reviewers decide what can be used, shared, or escalated.
Models, commissioning, and protection context	Model/version records, change logs, commissioning tests, settings evidence, and documented assumptions.	Flag mismatches between event evidence and documented context without approving settings or models.	Formal studies, compliance, legal, protection, and interconnection approvals stay outside the tool.

This checker is a client-only planning aid: no uploads, cookies, analytics, server submission; not root-cause authority, EMT/RMS simulation, NERC compliance/legal advice, protection-setting approval, interconnection approval, or autonomous operations.

Inverter-based resource events are not just signal events. They are evidence events.

A useful review may need relay records, PMU data, inverter or controller logs, plant-level records, model versions, commissioning tests, protection context, power-quality notes, timestamps, operating conditions, and human reviewer notes. For a TSO, DSO, generator, renewable operator, or reliability team, the hard part is often not a lack of data. It is packaging the right data with enough provenance to make the next review meeting productive.

Use the checker above as a client-only planning aid. It does not upload files, submit data, provide root-cause authority, run EMT or RMS simulations, provide NERC compliance or legal advice, approve protection settings, approve interconnections, or authorize operations.

Why IBR event evidence is different

Traditional grid events can already be difficult to hand off between operations, protection, planning, reliability, assets, and field teams. IBR events add more layers:

• Converter controls and firmware versions.
• Plant-level controller behavior.
• Model and study assumptions.
• Disturbance ride-through context.
• PMU, relay, and controller timestamp alignment.
• Power-quality and oscillation notes.
• Commissioning and change-log evidence.
• Interfaces between asset owners, utilities, and reliability teams.

NERC’s public IBR performance work and Project 2023-02 show why this is a priority area. IEEE 2800 and IEEE 1547 provide important public anchors for IBR and DER performance expectations, but a GridAPM article should not imply standards certification or compliance advice.

What agentic AI can help with

Agentic AI is useful when it does bounded evidence work:

• Create a source inventory for one event class.
• Draft a timeline with timestamp uncertainty clearly marked.
• List missing records by source owner.
• Separate event facts from assumptions.
• Compare model, controller, and commissioning evidence at a high level.
• Prepare reviewer questions for reliability, protection, operations, and owner teams.
• Preserve which claims were approved, edited, rejected, or escalated.

That workflow can save time without replacing the people responsible for engineering conclusions.

IBR event evidence matrix

Evidence area	Records to gather	Agentic AI assist	Human approval boundary
Disturbance timeline	Event start, trip, ride-through, alarm, relay, PMU, controller, and operator timestamps.	Draft a timeline and mark alignment gaps.	Reliability or operations reviewer validates timeline meaning.
IBR controller context	Inverter logs, plant controller logs, firmware, settings context, and change records.	List source gaps and version conflicts.	Owner and qualified engineering teams approve interpretation.
Model and study context	Model version, study assumptions, validation notes, commissioning records, and known limitations.	Summarize available evidence and missing validation context.	Planning and study teams control model conclusions.
Protection and PQ context	Relay events, protection records as read-only context, harmonics, voltage, frequency, and oscillation notes.	Prepare review questions and handoff notes.	Protection and PQ specialists approve next actions.

What not to automate

IBR evidence workflows should not be positioned as:

• Root-cause authority.
• EMT or RMS simulation.
• Protection-setting approval.
• Interconnection approval.
• NERC compliance or legal advice.
• Autonomous curtailment or operations.
• Final reliability determination.

The safer story is also more useful: GridAPM can help turn scattered event evidence into a review-ready package with source links, gaps, reviewer questions, and clear approval states.

A pilot scope that is narrow enough

A practical first pilot can target one event class, one owner group, or one review interface.

Example scopes:

• One renewable fleet event evidence package template.
• One disturbance timeline drafting workflow.
• One protection-to-planning handoff package.
• One model/version evidence inventory.
• One cross-functional closeout learning workflow.

Success metrics should be operational:

• Time to assemble event evidence.
• Number of missing-source questions found before the meeting.
• Timestamp alignment gaps identified.
• Reviewer edits and rejected AI statements.
• Clarity of final handoff package.

How GridAPM helps

GridAPM can help utility and energy teams evaluate IBR evidence workflows by organizing approved sources, creating gap lists, drafting review questions, and preserving human approval states. This complements GridAPM’s existing focus on transformer APM, DER/load visibility, event handoffs, and local-first evidence packs.

Useful internal links include the grid event handoff checklist, DER and load visibility scoper, utilities solution, integrations, security, data handling, pilot evaluation, and sample evidence pack.

The IBR evidence principle

An AI agent should make the event evidence easier to inspect. It should not become the event authority.

That is the practical GridAPM position: source-linked evidence, reviewer-controlled interpretation, and audit-ready handoffs for critical energy workflows.

Frequently asked questions

Does the IBR checker identify root cause?

No. It scopes event evidence readiness only. It does not perform root-cause analysis, EMT or RMS simulation, compliance advice, protection-setting approval, or operational approval.

What evidence is useful for IBR event review?

Useful evidence can include event timestamps, relay and PMU records, inverter/controller logs, model and version records, commissioning tests, power-quality notes, protection context, contact paths, and reviewer authority.

How can GridAPM help IBR event teams?

GridAPM can help organize approved event evidence, draft missing-data questions, preserve source provenance, and route review packages to qualified human reviewers.
