Description
In this paper zone reactive power controller is presented. Power network is naturally divided into voltage areas which are semi-independent or, at least, have no significant impact on neighbouring areas. Natural voltage areas, zones, represent the impact range of control actions performed in a certain zone. Control actions influence is small in neighbouring zones. Each zone is characterized by the pilot node (PN) voltage value (or profile) which is maintained by coordinated action on control equipment and generators in the zone. Additional zone reactive power controller is introduced which reduces reactive power exchange with neighbouring zones if there is sufficient reactive power and voltage reserve in order to minimize losses due to reactive power flows. Simulations are performed to demonstrate the effectiveness of the solution as well as advantages and disadvantages.
