Course: Power System Design credits: 5

In this module, an energy system is designed. Components for energy infrastructure are integrated with additional systems to transport energy over long distances. 

Professional Products 

• Energy-technical simulations and calculations: The methods and processes by which the behaviour, performance and efficiency of energy-related systems or components are analysed and predicted. This includes the use of mathematical models, numerical methods and software tools.  In this module: calculations and simulation of loadflow, short-circuit, arcflash, protection and selectivity in energy systems. 
• System design – An overview of components and interactions between different components of a system. It includes the design of software and hardware architecture, components, interfaces, and data. In this module: AC and DC grids, with renewable sources and storage. 

Skills 

• Making component and design choices – The process of evaluating and selecting alternatives during the design process, based on criteria such as functionality, cost, sustainability, and aesthetics, to achieve an optimal solution. This can be done, for example, with the help of a pugh matrix or a morphological overview. 
• Selection of power components – The process of choosing suitable electrical and electronic components, such as transformers, power electronics (IGBTs, MOSFETs), switches, and capacitors, based on requirements such as power, voltage, amperage, efficiency, thermal management, and reliability within an energy or power system. 
• Selection of components for energy infrastructure – The process of choosing suitable electrical and mechanical components, such as transformers, switches, cables, inverters, and protection systems, based on technical requirements, capacity, reliability, durability, and regulatory compliance, in order to guarantee a stable and efficient energy system. 
• Energy-technical simulating and calculating: The methods and processes by which the behaviour, performance and efficiency of energy-related systems or components are analysed and predicted. This includes the use of mathematical models, numerical methods and software tools. In this module: calculations and simulation of loadflow, power flow, short-circuit, arcflash, protection and selectivity in energy systems. 

Knowledge 

• Components of energy systems – The parts that work together to generate, convert, transport, distribute and consume energy. This includes energy sources (such as solar panels and wind turbines), converters (such as inverters and current and power transformers), storage (such as batteries), distribution networks (such as HV/LV cables and (HV) switches and fuses) and end-user equipment. 
• The structure of the electricity grid – The construction and organisation of the network that generates, transports and distributes electricity from energy sources to end users. It consists of generation power plants, high-voltage networks for transport, medium-voltage networks for regional distribution, and low-voltage networks for end users, with supporting components such as transformers, switches and control stations. 
• Grid stability of an electricity grid – The ability of the power grid to absorb disturbances and fluctuations in supply and demand, while keeping voltage and frequency within safe limits. This includes aspects such as frequency stability, voltage stability and rotor angular stability, and is influenced by factors such as generation, loading, grid structure and control strategies. 
• Electricity Grid protection – The implementation of systems and devices to detect and respond to short-circuits, arc flashes and other faults in the electricity grid. It ensures protection by isolating faulty sections using circuit breakers, relays, and fuses, preventing damage and maintaining safety. Selectivity is a key principle, ensuring that only the affected part of the grid is disconnected while the rest remains operational, minimizing disruptions.
