Interconnection of small, modular generation to low voltage distribution systems can form a new type of power system, the microgrid. Microgrids can be operated connected to the main power network or autonomously, similar to power systems of physical islands, in a controlled, coordinated way.

1.2.1 Technical, economic and environmental benefits
• Energy efficiency
• Minimisation of the overall energy consumption
• Improved environmental impact
• Improvement of energy system reliability and resilience
• Network benefits
• Cost efficient electricity infrastructure replacement strategies
• Cost benefit assessment

1.2.2 Technical challenges for microgrids
• Relatively large imbalances between load and generation to be managed
• Presence of power electronic interfaces
• Protection and safety
• Specific network characteristics
• Use of different generation technologies
these are microgrid for systems in local
