3 Some Hatch Projects for Remote Mines and Communities

4 Hybrid Power System - Essentials

5 Requirements for High Penetration Total load = Total production at all times. Maintain sufficient Spinning reserve such production can meet varying loads or Curtail Renewable Power Design with sufficient generation Ramp rates to meet the maximum variations Implement Load shedding if total load not met. Respect the Time to required start a Genset Energy Storage Required: Spinning reserves, Maintain load during the time it takes to start a genset, To minimize variability from renewable powers. Provide additional Reactive Power to maintain Power Factors Smart Controls to dispatch Gensets, Energy Storages and Renewable Powers

6 Energy Storage Systems Hydrogen storage tanks Flywheel and electrical substation Battery system Fuel Cells Electrolyser Courtesy of Tugliq Photographer Justin Bulota

7 Storage 3 USE CASES: Smooth Power//backup Power//Store Wind Power Excess Excess Energy (about 300 kw or 7.2 MWh per day) Opportunity to stop a Genset of 1.5 MW Backup Power needed the time to restart the Genset

8 Energy Storage Controller Dispatched

9 Operations Genset operators (mine, utility) also control the amount of wind power to be integrated Energy Storage Operation fully automatized 24/7 remote monitoring (First line & Second line support) of equipment status Continuous Improvement to acheived optimized operation

10 Last Words Hybrid Power lower the cost of energy and reduce carbon footprint Energy Storage is required For Grid Stability To Reduce Wind Power Curtailment Microgrid controller needed To ensure a great successful project: Design, Design, Design with experience the appropriate system (sizing, controls, optimal system the reduce energy storage aging).

16 High Penetration Challenges Respect Constraint of Operation on genset Operate Genset withing an acceptable range (from 70% to 100% its capacity factor) to prevent internal glazing and carbon buildup and to stay within efficient operation range. Maintain spinning reserves to cope with load changes Maintain Grid stability Maintain Frequency and Voltage within an acceptable range Maintain Harmonics and power factors at acceptable levels Grid is typically robust initially and most remain robust to strong wind power variability Events to Consider: Major Icing events (sudden stop) Turbulent wind (v.g.: during blizzards) Cut-off wind speed (sudden stop) Trip events
