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
