Abstract
: The promotion of renewable energy in distant areas faces problems with mismatch between generation and grid. Because the local demand is not enough to accommodate variable renewable energy, a proportion of renewable power need to be transmitted to external power systems via the local grid besides consumed by the local load, which poses a great challenge to the security control of the local grid. Such a relationship is called “coupling”. To reduce the side effect of coupling in the stage of transmission planning, we firstly proposed coupling evaluation indicators in the perspective of the grid structure and system operation states and then presented a method to implement evaluation based on the economic dispatch model considering system's mitigation against fluctuations. Finally, a transmission expansion planning (TEP) method is proposed with the inclusion of coupling evaluation and the consideration of a hybrid AC/DC transmission system. The case study demonstrates the coupling and shows that hybrid AC/DC transmission is better when coping with such a situation than AC transmission system.
