A novel scheduling and obligatory electricity off-take system for wind power plants

The Hungarian legislation system concerning wind power is often cited as the one that did not reach its goal. On one hand, scheduling accuracy of wind power plants falls short of similar data of foreign units; on the other hand, introduction of the penalty tariff did not prove to be effective to reverse this process. Trying to solve the twofold problem at once, in present paper the authors propose a new obligatory electricity purchase and scheduling system, which allows the transmission system operator (TSO) to decrease the amount of control reserves required by wind power plants. The two new elements of the system are the scheduling characterised by a level of uncertainty and the differentially rewarding tariff system, using two tariffs (Base and Bonus). Besides creating the lacked motivation for operators, with the conditions of the Bonus tariff, financial assets are available to cover the cost of the use of unforeseen control reserves.
