6 Microgrids and renewable energy integration Secure power generation and fuel cost savings Assumption based on IEA International Energy Outlook Fuel cost is volatile and rising over time Renewable energy costs are less volatile and economically competitive today Steady decline of renewable energy levelized cost of electricity is opening new market opportunities Source: Lazard s levelized cost of energy analysis v8.0 An optimized energy mix leads to a lower levelized cost of electricity Wind LCOE decrease from 2009 to 2014 PV LCOE decrease from 2009 to 2014 Slide 6

7 Renewable energy integration challenges Managing power output fluctuations Solar power variations Wind power variations Inherent volatility of renewable energy (RE) can compromise grid stability The RE integration solution must address requirements traditionally fulfilled by diesel generation (base load) Frequency and voltage control Sufficient spinning reserve Sufficient active and reactive power supply Peak shaving and load levelling Load sharing between generators Fault current provision RE generation capacity should be sized to maximize ROI and fuel savings Slide 7 ROI: Return on investment

11 Microgrid Plus System Central vs. networked control systems Controller failure System maintenance Upgrades Future extensions Central control systems Failure of the central master controller can be catastrophic System maintenance requires complete shutdowns Modification requires extensive testing Scalability and expansion is a complex and expensive task Microgrid Plus System The failure of one controller has a minimal impact. Replacement capacity can be brought online immediately Parts of the system can be shut down while the rest of the system continues to operate independently Easy upgrades thanks to independence and modularity The system is more scalable and extendable (not limited to on-board I/O of central master controller) A networked architecture ensures maximum reliability and the most cost effective solution Slide 11

12 PowerStore Grid stabilization Compact and versatile grid stabilizing generator capable of stabilizing power systems against fluctuations in frequency and voltage The PowerStore consists of: Flywheel energy storage Power converter system Operator interface The PowerStore is able to operate in: Grid Support Mode (GSM) for large networks Virtual Generator Mode (VGM) for isolated microgrids Slide 12
