ELEE 4115U Fundamentals of Smart Grid Copyright 2016 2 Dr. Walid G. Morsi Fall 2024 Legacy Electric Power System o Legacy electric power systems, which have developed over the past 70 years, feed electrical power from large central generators up through generator transformers to a high voltage interconnected network, known as the transmission grid. o Each individual generator unit, whether powered by hydropower, nuclear power or fossil fueled, is large with a rating of up to 1000 MW. o The transmission grid is used to transport the electrical power, sometimes over considerable distances, and this power is then extracted and passed through a series of distribution transformers to final circuits for delivery to the end customers.

Morsi Fall 2024 Smart Grid Driver Operational Security of Constraints Supply Ending the Aging Assets Reliance on Imported Oil Thermal Smart Digital Grade Power Constraints Grid Quality ELEE 4115U Fundamentals of Smart Grid Copyright 2016 4 Dr. Walid G. Morsi Fall 2024 Smart Grid Definitions o European Technology Platform: "A Smart Grid is an electricity network that can intelligently integrate the actions of all users connected to it - generators, consumers and those that do both - in order to efficiently deliver sustainable, economic and secure electricity supplies." o US Department of Energy: "A smart grid uses digital technology to improve reliability, security, and efficiency (both economic and energy) of the electric system from large generation, through the delivery systems to electricity consumers and a growing number of distributed-generation and storage resources." o Smarter Grid:The Opportunity "A smart grid uses sensing, embedded processing and digital communications to enable the electricity grid to be observable (able to be measured and visualized), controllable (able to manipulated and optimized), automated (able to adapt and self-heal), fully integrated (fully interoperable with existing systems and with the capacity to incorporate a diverse set of energy sources)." ELEE 4115U Fundamentals of Smart Grid Copyright 2016 5 Dr. Walid G. Morsi Fall 2024 Early Smart Grid Initiatives o Active Distribution Networks o Power flow is not unidirectional o distributed generators give rise to a wide range of fault currents and hence complex protection and coordination settings are required to protect the network o the reactive power flow on the network can be independent of the active power flows o many types of DGs are interfaced through power electronics and may inject harmonics into the network Distribution network active management scheme ELEE 4115U Fundamentals of Smart Grid Copyright 2016 6 Dr. Walid G. Morsi Fall 2024 Early Smart Grid Initiatives o Active Distribution Networks: Distribution Management System Controller (DMSC) o The DMSC obtains measurements from the network and sends signals to the devices under its control. Control actions may be a transformer tap operation, altering the DG output and injection/absorption of reactive power. o The DMSC controller building blocks can assess operating conditions and find the control settings for devices connected to the network. o The key functions of the DMSC are state estimation, bad data detection and the calculation of optimal control settings ELEE 4115U Fundamentals of Smart Grid Copyright 2016 7 Dr. Walid G. Morsi Fall 2024 Early Smart Grid Initiatives o Virtual Power Plant (VPP) o The concept of a Virtual Power Plant (VPP) is to aggregate many small generators into blocks that can be controlled by the system operator and then their energy output is traded. o The VPP concept allows individual DERs to gain access to and visibility in the energy markets. o Furthermore, system operators can benefit from the optimal use of all the available capacity connected to the network Source: Siemens Energy ELEE 4115U Fundamentals of Smart Grid Copyright 2016 8 Dr. Walid G. Morsi Fall 2024 Technologies Required For the Smart Grid o Information and Communications Technologies: o two-way communication technologies to provide connectivity between different components in the power system and loads o open architectures for plug-and-play of home appliances; electric vehicles and microgeneration; o communications, and the necessary software and hardware to provide customers with greater information, enable customers to trade in energy markets and enable customers to provide demand- side response; o software to ensure and maintain the security of information and standards to provide scalability and interoperability of information and communication systems.
