Microgrids and renewable energy integrationSecure power generation and fuel cost savings
| Slide 6© ABB Group
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
An optimized energy mix leads to a lower levelizedcost of electricity
Assumption based on IEA International Energy Outlook
Wind LCOE decrease from2009 to 2014
PV LCOE decrease from2009 to 2014
Source: Lazard’slevelized cost of energy analysis v8.0
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

Microgrid Plus system PowerStore
Specially designed networked control system responsible for coordinating the operation of hybrid power stations
Grid stabilizing system that offers real and reactive power to enable intermittent renewable energy to be integrated into grids
• Maximizes fuel savings• Optimizes use of renewable energy• Guarantees optimum loading and spinning
reserve in fossil fuel generators• Distributed logic enhances reliability and
scalability for future system expansions
• Can be used in isolated grids or in grid support mode
• Maximizes fuel savings through highest possible renewable penetration
• Ensures high power quality by stabilizing renewable energy generation

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