With large scale wind power integration, system operators are now facing more uncertain factors in power dispatch and reserve decision. This paper analyzes the influencing factors in power reserve decision. Deterministic and probabilistic methods of reserve decision are summarized, especially their differences and characteristics. The problem of reserve configuration can be achieved both from demand side and power supply side with some feasible options such as the combination of wind and thermal power, electric vehicles and other energy storages. Considering the influence of power system production, operation, and consumption comprehensively with large scale wind power integration, the general concept of power reserve is extended based on all the above.
