Integration of Large Scale Wind Energy with Electrical Power Systems in China
Description
* Presents the challenges of electrical power system planning, design, operation and control carried out by large scale wind power, from the Chinese perspective
* Focuses on the integration issue of large scale wind power to the bulk power system, probing the interaction between wind power and bulk power systems
* Wind power development is a burgeoning area of study in developing countries, with much interest in offshore wind farms and several big projects under development
* English translation of the Chinese language original which won the "Fourth China Outstanding Publication Award nomination" in March 2013
