      Coordination and control of distributed energy resources for provision of ancillary services 

      Domínguez-Garcia, A. D.; Hadjicostis, Christoforos N. (2010)
      This paper discusses the utilization of distributed energy resources on the distribution side of the power grid to provide a number of ancillary services. While the individual capability of these resources to provide grid ...

      Small inverter-interfaced distributed energy resources for reactive power support 

      Domínguez-Garcia, A. D.; Hadjicostis, Christoforos N.; Krein, P. T.; Cady, S. T. (2011)
      The use of small inverter-interfaced distributed energy resources for reactive power support is discussed. While the primary function of these resources is to deliver active power, they can also be used to provide reactive ...

      Upper and lower bounds on fsm switching activity 

      Athanasopoulou, E.; Hadjicostis, Christoforos N. (2003)
      This paper obtains upper and lower bounds for the switching activity on the state lines of a finite state machine (FSM) that is driven with typical input sequences. By exploiting the symmetries between the Hamming distances ...
