Identifies the forecast information used by the assigned forward-looking dispatch calculation.

## In plain English

### What this block does

Identifies the forecast information used by the assigned forward-looking dispatch calculation.

### A simple example

In a microgrid with solar generation, the controller can restrain inverter output when local load and storage cannot absorb the available power. The resource controller reports its own availability and accepted operating limits. For this reference, the drawing identifies “Solar forecast and validity” at the input and “Dispatch forecast input” at the output. A forecast is not an operating measurement.

### What the drawings help you do

Start at the named input: Solar forecast and validity. Identify its source device or document and the state represented on the drawing. Follow the named output: Dispatch forecast input. Cross-reference its destination and separate the command from confirmation that the equipment responded.

### Terms

- Input: Solar forecast and validity
- Output: Dispatch forecast input
- Application reference: An explanation of a named drawing function or circuit relationship; the project documents define the equipment and its connections.

## What it represents

Identifies the forecast information used by the assigned forward-looking dispatch calculation. Renewable-generation coordination connects variable resource availability, inverter operating limits and the microgrid power target. Available solar or wind power, an issued curtailment request and actual delivered power are different signals.
In a microgrid with solar generation, the controller can restrain inverter output when local load and storage cannot absorb the available power. The resource controller reports its own availability and accepted operating limits. For this reference, the drawing identifies “Solar forecast and validity” at the input and “Dispatch forecast input” at the output. A forecast is not an operating measurement.
Identify the point where power is measured and the system declaring each availability or limit signal. Resource forecasts and controller requests do not guarantee the delivered generation at every instant. The functional block is an independent explanation of this named application. Equipment-specific ratings, terminal connections and operating conditions must be established in the project documentation.

## How to read it

- Start at the named input: Solar forecast and validity. Identify its source device or document and the state represented on the drawing.
- Follow the named output: Dispatch forecast input. Cross-reference its destination and separate the command from confirmation that the equipment responded.
- A forecast is not an operating measurement.
- Identify the point where power is measured and the system declaring each availability or limit signal. Resource forecasts and controller requests do not guarantee the delivered generation at every instant.

## Information to show or reference

- Label the source and connection reference for solar forecast and validity.
- Identify the destination and defined state of dispatch forecast input.
- Record the equipment or control-document revision supporting this functional block.
- Check this application limit in the project design: A forecast is not an operating measurement.

## Important distinction

A forecast is not an operating measurement. This reference describes the named application; it does not establish a new IEC graphical symbol, an ANSI device-function number or an exact manufacturer connection diagram.
