Power quality has emerged as a challenging area in the context of deregulation, wherein electricity distribution buyers and sellers carry out mutually agreed-upon exchanges. A market for active power and reactive power is installed in many places as a result of a deregulation process. However,...

This paper presents new concepts and methodological tools to decide the investments that electric distribution utilities must perform under regulatory frameworks based on performance (Performance Based Regulation or PBR). The proposal is focused on short-term investments. In this work, the...

The economic development can’t be achieved without increasing the energy efficiency. Thus will be insured the uncoupling of energetic resources consumption increase by the economic growth. By reducing energy consumption the economic efficiency increase, also a better environment protection and...

The operation of wind turbines in the distribution networks may affect the power quality offered to the consumers. One of the most important considerations is the effect on the voltage profile, i.e. the induced slow voltage variations, which are the subject of this paper. Two alternative...

This paper proposes an auto-adaptive controller that enables to suitably manage the reactive power supplied by the inverters of PV units whishing to provide the reactive power ancillary service on the base of standard needs or on a voluntary basis. The derived controller is based on an...
