The fundamental condition for a safely operating power-system the balance between the power produced by the power-plants and the power consumed by the consumers. The variance from the system frequency is also important, it can't exceed a certain degree. Having regulatory reserves is necessary.

Recently the competitive market situation formed on the field of system-wide services and the exclusion of cogeneration units from the KÁT balance group made the minor power-plants which are gaining increased role in the Hungarian energy production face a new situation. The response of the minor plants to these changes were the collaboration, creating regulatory centers. Thanks to these centers the transmission system operator acquired significant new regulatory reserves which was necessary because of the aging of the Hungarian power-plants and the increasing number of plants using renewable energies, within it wind.

In this thesis the operation of system-wide regulations are presented accordingly, paying particular attention to introduce reserve markets. I examine the cause of newly found regulatory centers and their role in electricity system.

In the final part of this thesis I made a new algorithm for the agen-based software created in the department, which is intended to simplify the regulatory centers' dispatching tasks.
