Electric power networks consist of elements that generate electricity and deliver it to end-users. Contemporary power systems typically include six key elements: 1) generating stations that produce electricity, 2) voltage-regulating transformers, 3) high-voltage transmission cables, 4) substations that reduce voltage for distribution networks, 5) distribution cables, and 6) local transformers that adjust voltage for household appliances. While electricity generation and transmission are cost-effective processes, electrical energy differs from other energy types as it cannot be readily stored, requiring generation to match real-time consumption.
At NC State, investigations into power systems focus on analyzing innovative technologies including power electronics, storage solutions, and renewable energy sources, examining their impact on power grid functionality, management, and safety mechanisms.
