Distributed generation is _________generation.
Small scale (11 kV)
Large scale (415 V)
Both A and B (132 kV)
None of the above
Small scale (11 kV)
Distributed Generation (DG) refers to small-scale power generation technologies used to provide electricity at or near the site of consumption. Unlike centralized generation, which involves large-scale power plants, DG utilizes modular units such as solar PV, wind turbines, or small diesel generators typically connected to the distribution network (e.g., at 11 kV or lower voltage levels).

DG operates by integrating modular energy sources directly into the distribution grid, reducing transmission losses and improving power quality. It functions by allowing bidirectional power flow, where excess energy from local generation can be exported back to the main utility grid, often utilizing power electronics converters to match frequency and voltage synchronization requirements.
Reduces transmission and distribution (T&D) losses by producing power near the load.
Improves reliability and voltage profile of the distribution system.
Reduces the necessity for expanding large transmission infrastructure.
Often includes renewable energy sources like solar and wind (Non-conventional).
Lower transmission losses
Enhanced power supply reliability
Reduced capital expenditure on transmission lines
Protection coordination becomes complex due to bidirectional power flow
Integration challenges with intermittent sources
Voltage stability issues under high penetration
Microgrids
Industrial captive power plants
Rural electrification
Large-scale generation usually operates at transmission voltage levels, often exceeding 132 kV, which is contrary to DG characteristics.
DG is sometimes referred to as 'embedded generation' or 'decentralized generation'.
A is correct тАФ Distributed generation specifically refers to small-scale power generation units, typically connected to the distribution network (e.g., 11 kV or 415 V).
Always remember that DG is linked to distribution levels; transmission levels (132 kV+) are reserved for centralized bulk generation.
