Definition:
Small-scale units of local energy generation connected to the grid at the distribution level, including technologies like solar panels, wind turbines, and energy storage systems.
Key Components:
- Solar PV & Wind Power: Renewable generation sources.
- Battery Energy Storage: Stores excess power for later use.
- Microgrids & Smart Inverters: Enhances grid interaction and control.
- Demand Response Integration: Supports grid stability by adjusting power consumption.
Use Cases/Industries:
- Commercial & Industrial Buildings: Reducing energy costs with self-generation.
- Remote & Island Communities: Providing energy independence from central grids.
- Electric Vehicle Charging Networks: Integrating renewable power for sustainable transportation.
Advantages:
- Enhances Grid Resilience: Reduces reliance on centralized generation.
- Optimizes Energy Costs: Reduces electricity expenses for consumers.
- Supports Renewable Integration: Enables greater use of clean energy.
Challenges:
- Intermittency & Grid Compatibility: Requires smart systems to balance supply and demand.
- Regulatory Barriers: Market policies may limit DER deployment.
