On spinning reserve determination and power generation dispatch optimization for wind power integration systems

A joint optimization dispatching model of active power and AGC for wind power integration systems is proposed. In the mathematical model, both the probabilistic distributions of load and wind forecast errors are introduced to deal with the uncertainties. To make the optimization results more rational, an approach on spinning reserve determination for wind power integration systems is presented based on a given risk level. To describe the operation state more accurately, a method of multi-scenario is adopted and the actual output of AGC generators will be adjusted according to the AGC unit modification strategy in each scenario. The case studies are carried out on a system with 10 AGC units and a wind farm. Compared to conventional dispatch method, the results show that the proposed optimization model is rational.
