Abstract

In the power system, an increasing amount of distributed energy resources and major changes of reactive power quality have been observed. Thus, Distribution System Operators (DSOs) are to improve and modify their reactive power management. An additional motivation is the remarkably risen costs caused by an excessive and altered flow of reactive power.The paper describes how Helen Electricity Network Ltd., the local DSO of Helsinki, Finland, manages the compensation of reactive power in an urban city network by various means. Furthermore, the paper introduces as a novel approach for reactive power management a concept of an ancillary reactive power market. This is seen as a possible future development if the existing markets and regulations advance. This paper was being carried out under the Finnish demonstration of EU-SysFlex project in Helen Ltd. and in Helen Electricity Network Ltd.
