👉 Reserve engineering is a critical aspect of power system design and operation, focusing on ensuring reliability and continuity of electricity supply. It involves the strategic planning and implementation of backup resources, such as additional power generation units, transmission lines, substations, and control systems, that can be quickly activated in the event of a primary system failure or unexpected demand surge. These reserves are designed to maintain grid stability, prevent blackouts, and ensure uninterrupted service to consumers. There are typically two types of reserves: spinning reserves, which are available immediately but may not be fully utilized due to their operational status, and non-spinning reserves, which are activated only when needed and may take longer to mobilize. Effective reserve engineering requires careful analysis, optimization, and coordination to balance cost-effectiveness with system reliability.
