# Microgrid storage dispatch tracking monitor Canonical URL: https://eloragrid.ai/symbols/microgrid-storage-dispatch-tracking-monitor Publisher: Elora Grid Updated: 2026-11-03 Lookup label: MSDTM Drawing use: Schematic Reference families: Manufacturer Representation: Functional block Installation focus: microgrids Input: Storage target and measurement Output: Storage power tracking error Compares the assigned storage power target with the measured AC or DC response at its defined boundary. ## In plain English ### What this block does Compares the assigned storage power target with the measured AC or DC response at its defined boundary. ### A simple example In a microgrid with a battery energy storage system, the controller can request discharge to support a power deficit while the battery management and conversion systems enforce their own operating limits. For this reference, the drawing identifies “Storage target and measurement” at the input and “Storage power tracking error” at the output. Measurement boundaries must match the target basis. ### What the drawings help you do Start at the named input: Storage target and measurement. Identify its source device or document and the state represented on the drawing. Follow the named output: Storage power tracking error. Cross-reference its destination and separate the command from confirmation that the equipment responded. ### Terms - Input: Storage target and measurement - Output: Storage power tracking error - Application reference: An explanation of a named drawing function or circuit relationship; the project documents define the equipment and its connections. Concept diagram: Storage target and measurement → MSDTM → Storage power tracking error A reading guide. The entry's original illustration and input/output facts describe this application. - [Avista Shared Energy Economy microgrid protection and control case study](https://selinc.com/api/download/135486/) ## What it represents Compares the assigned storage power target with the measured AC or DC response at its defined boundary. Storage coordination combines the battery's energy limits with the converter's electrical capability and the microgrid's operating demand. State of charge, allowable power and connection status describe different aspects of availability. In a microgrid with a battery energy storage system, the controller can request discharge to support a power deficit while the battery management and conversion systems enforce their own operating limits. For this reference, the drawing identifies “Storage target and measurement” at the input and “Storage power tracking error” at the output. Measurement boundaries must match the target basis. Show which system declares each limit and which controller receives the target. Battery protection, converter capability, thermal management and emergency responses remain with the selected system design. 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: Storage target and measurement. Identify its source device or document and the state represented on the drawing. - Follow the named output: Storage power tracking error. Cross-reference its destination and separate the command from confirmation that the equipment responded. - Measurement boundaries must match the target basis. - Show which system declares each limit and which controller receives the target. Battery protection, converter capability, thermal management and emergency responses remain with the selected system design. ## Information to show or reference - Label the source and connection reference for storage target and measurement. - Identify the destination and defined state of storage power tracking error. - Record the equipment or control-document revision supporting this functional block. - Check this application limit in the project design: Measurement boundaries must match the target basis. ## Important distinction Measurement boundaries must match the target basis. 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. ## Facts - Representation: Functional block - Installation focus: Microgrids - Input / boundary: Storage target and measurement - Output / connection: Storage power tracking error - Lookup label: MSDTM is a library lookup label, not a standard device designation. ## Public references - [Avista Shared Energy Economy microgrid protection and control case study](https://selinc.com/api/download/135486/) — SEL.
