1. The penetration levels of power generation from variable renewable energy sources such as wind and solar energy into the power systems are increasing progressively. However, the power generation capacity of renewable energy sources is hardly predictable, creating uncertainty on the supply side. Thus, the reliability of renewable energy sometimes becomes questionable. Analyze and describe the reliability and challenges of renewable energy penetration on the general power system.

Discuss the concept of smart grids and their role in improving the efficiency and reliability of power systems.

Electricity Distribution Network - What are the UK power distribution network voltage levels? Why there is the need for a distribution management system in electric power distribution networks? Power System Operation and Control - State three reasons why it is important to maintain the supply frequency within statutory limits for a power system. Power System Operational Issue - Briefly discuss what are the major power quality issues, particularly in power-electronic-interfaced Microgrid systems. New Electricity Demand - Briefly explain the concept of plug-in hybrid electric vehicle technology and its challenges to the power grid. Power System Operational Issue - Briefly explain the concept of Dynamic Network Rating (DNR), and what are the major benefits for electricity distribution networks and distribution network operators (DNOs). Electricity Network Operation with High Penetration Level of Renewables Although wind power is seen as offering many countries the potential to reduce…

Discuss the role of renewable energy sources like solar and wind in modern power systems and the challenges they pose for grid integration.
