Micro and Local Power Markets

Introduces readers to micro and local power markets and their use for local initiatives, grid integration, and future applications

This book provides the basis for understanding micro power markets, emphasizing its application for local initiatives, the grid integration of renewable-based generation, and facilitating the decarbonization of the future electrical networks. It gives readers a comprehensive overview of the market operation, and highlights the basis of the design of local and micro markets.

Micro and Local Power Markets starts by covering the economics and basic principle of power markets, including the fundamentals of the power trading (for both wholesale and local markets). Following a definition of both micro and local (technical and economic aspects) power markets, the book then looks at the organization of such markets. It describes the design of those power markets, isolated from the wholesale markets, and examines the methodologies of the interaction between these power markets and wholesale markets. The book also presents cognitive business models for micro and local power markets, as well as the regulatory issues concerning them.

• Introduces the basic principle of power markets

• Defines micro and local power markets

• Outlines the design of micro and local power markets, including the principles, as well as the trading schemes, flexibility, and services

• Discusses methodologies of the interaction between micro and local power markets and wholesale markets

• Presents business models for micro and local power markets

• Summarizes regulatory issues around micro and local power markets

Micro and Local Power Markets is an ideal book for upper undergraduate students in engineering, as well as for early researchers in the energy sector. It is also recommended for any scientist and engineer being introduced to the field of power systems and their organization.
