A standard expected value model for multi-objective multi-stage transmission planning is presented to realize the transmission optimal planning with the control of line overloading risks. In this model, a constraint of overloading risks is built with expected value and standard deviation of random line active power and two objectives are given as expected value of the average power loss and discount value of the investment cost. By modeling uncertain informations with probability theory, the probabilistic DC power flow is adopted for the correlated calculations among random variables in the planning model.4 A novel multi-objective transmission planning approach that considers transmission investment profit is proposed. Requests for transmission investment profit and social welfare are involved in the proposed planning approach.

This invention concerns a current control process for a feed-in voltage converter, wherein a detected flux-inducing current component and a detected torque-inducing currrent component of an actual currrent vector of a rotating field machine are each controlled for a flux-inducing current component set value and a torque-inducing current component set value of the rotating field machine. To that effect, a control set-value (DELTA u*sp, DELTA u*sq) is determined, dependent each time upon a determined current component control deviation. From these, current components of an actual current vector are formed each time by overlay of a formed pilot value (u*spvor, u*sqvor). This invention also concerns a device for carrying out this process.
