Integrating a high share of renewable energy into the grid brings with it a host of technical challenges, and a lack of widespread understanding of these issues is felt to be slowing the development of sustainable energy projects in many countries including China.
These issues cluster into questions around ancillary services, or how to support the transmission of electric power from seller to buyer purchaser in a complex environment where many parties are involved and reliability of service must be assured, and into the standards for the actual grid connection.
Presenting suggestions on the ancillary services in the smart grid and unifying the grid connection standards relating to renewable energy would help increase China’s share of renewable energy and reduce the country’s dependence on fossil fuels. One province in Northeast China will be selected for a case study on the topic. Based on this study, recommendations regarding ancillary services and grid connection standards for renewable energy will be proposed and validated.
