Step-by-Step Guide for Beginners: Setting Up OpenEMS Simulation Configuration - LeoXu - 11-19-2024 # **OpenEMS Simulation Configuration Steps** This guide provides step-by-step instructions for setting up and debugging OpenEMS simulations. --- ## **Step 1: Simulator App** - **Action**:   - Check `enable`.   - Click `save`. - **Notes**:   - This will clear all existing configurations. Ensure no critical data is lost before proceeding.   - After clearing, all essential settings must be reconfigured in sequence. --- ## **Step 2: Scheduler (All Alphabetically)** - **Settings**:   - `ComponentID: scheduler0`   - Check `enable`.   - Click `save`. - **Functionality**:   - Automatically starts the following core components in alphabetical order:     - `core`     - `ess power`     - `evcs power`     - `Controller Api Websocket`     - `log`   - **No additional configuration required** to ensure basic system functionality. --- ## **Step 3: Controller Debug Log** - **Settings**:   - `ComponentID: ctrlDebugLog0`   - Check `enable` and `Condensed output`. - **Functionality**:   - Enables debugging mode with condensed logs for troubleshooting and system analysis. --- ## **Step 4: Simulator DataSource (CSV Predefined)** Configure three data sources to simulate load, PV generation, and ESS data. 1. **Load Meter Data Source**:   - `ComponentID: datasource0`   - Configuration:     - Check `enable`.     - `Factor: 10000`     - `Time-Delta: -1`     - `Source: h0-summer-weekday-standard-load-profile.csv` 2. **PV Meter Data Source**:   - `ComponentID: datasource1`   - Configuration:     - Check `enable`.     - `Factor: 10000`     - `Time-Delta: -1`     - `Source: h0-summer-weekday-pv-production.csv` or `production2`. 3. **ESS Data Source**:   - `ComponentID: datasource2`   - Configuration:     - Check `enable`.     - `Factor: 10000`     - `Time-Delta: -1`     - `Source: h0-summer-weekday-pv-production2.csv`. --- ## **Step 5: Simulator GridMeter Acting** - **Settings**:   - `ComponentID: gridmeter0`   - Check `enable`. - **Functionality**:   - Simulates grid monitoring, providing data on grid power, state, and flow direction. --- ## **Step 6: Simulator EssSinglePhase Reacting** - **Settings**:   - `ComponentID: ess0`   - `Phase: L1` (single-phase setup; use L2 for two-way or L3 for three-phase setups).   - `Datasource-ID: datasource2`   - `Max Apparent Power [VA]: 10000`   - `Capacity [Wh]: 10000`   - `Initial State of Charge [%]: 30`   - `Grid mode: On_Grid` (enables grid interaction). - **Functionality**:   - Activates a single-phase ESS to simulate power response. --- ## **Step 7: Controller Ess Balancing** - **Settings**:   - `ComponentID: ctrlBalancing0`   - Configuration:     - `Energy System ID: ess0` (matches Step 6).     - `Grid Meter ID: gridmeter0` (matches Step 5).     - `Target Grid Setpoint: 10`. - **Functionality**:   - Controls ESS and grid meter to maintain balanced power flow. --- ## **Step 8: Controller Api Websocket** - **Check**:   - Ensure WebSocket is enabled. - **Functionality**:   - Facilitates communication between OpenEMS and the UI.   - The UI will not display system status if WebSocket is disabled. --- ## **Step 9: Simulator Battery** - **Settings**:   - `ComponentID: bms0`   - Check `enable`.   - Configure parameters:     - `Number of slaves: 1`     - `Discharge min voltage: 44`     - `Charge max voltage: 56`     - `Discharge max current: 50`     - `Charge max current: 50`     - `SOC: 75`     - `SOH: 95`     - `Temperature: 30`     - `Capacity KWh: 50`     - `Voltage: 5`     - `Min cell voltage mv: 3300`. - **Functionality**:   - Activates the battery simulator with customizable parameters. --- ## **Step 10: Simulator NRCMeter Acting** - **Settings**:   - `ComponentID: meter0`   - Check `enable`.   - Configuration:     - `Datasource-ID: datasource0`. - **Functionality**:   - Activates load meter simulation, linked to `datasource0`. --- ## **Step 11: Simulator Production Meter Acting** - **Settings**:   - `ComponentID: meter1`   - Check `enable`.   - Configuration:     - `Datasource-ID: datasource1`. - **Functionality**:   - Activates PV meter simulation, linked to `datasource1`. --- ## **Additional Recommendations** 1. **Step-by-Step Validation**:   - Save after adding or modifying each component.   - Use the OpenEMS WebSocket interface to verify component statuses incrementally. 2. **Log Monitoring**:   - Enable debug logs (Step 3) for detailed analysis of system interactions. 3. **Simulation Flexibility**:   - Adjust parameters like battery capacity, power limits, and load curves to better simulate real scenarios. 4. **Advanced Features**:   - Use custom data sources or scripts for extended simulation, e.g.:     - EV charging load simulations.     - Fault condition testing (e.g., disconnections, overload). By completing the above steps, the simulation system will be ready for testing and validation of complex scenarios.
