  • distributed reactive power generation Control for voltage rise mitigation in distribution networks
    IEEE Transactions on Power Systems, 2008
    Co-Authors: Pedro Carvalho, Pedro Correia, L A Ferreira
    Abstract:

    This paper addresses the problem of voltage rise mitigation in distribution networks with distributed generation. A distributed automatic Control approach is proposed to alleviate the voltage rise caused by active power injection. The objective of the proposed approach is not to Control Bus voltage but to guarantee that generator injections alone do not cause significant voltage rise: a solution in which distribution network operators (DNOs) are kept to their traditional task of voltage regulation for load demand. The approach is discussed in the perspective of effectiveness and adequacy. Its consequences to DNO Control effort are evaluated. Illustration is provided for a single feeder with stochastic generation and transformer on-load tap-changing voltage regulation.

  • Prioritizing Reactive power assignment strategy for doubly fed induction generator of Large-scale Wind Farm
    2010 Conference Proceedings IPEC, 2010
    Co-Authors: Ning Chen, Lingling Huang
    Abstract:

    In this paper the regional power grid voltage stability with the wind farm consisting of the VSCF doubly fed induction wind generator (DFIG) is presented. And proposed a Prioritizing Reactive power allocation strategy for Doubly fed induction generator of Large-scale Wind Farm. The strategy is mainly to get the wind farm reactive power requirements from the relative voltage offset of the voltage Control Bus,and assign reactive power generating mission to each DFIG considering its actual reactive power generating ability and the structure of electrical collection systems of the whole wind farm. The simulation result shows that the proposed strategy could fully take advantage of each DFIG's reactive power generating ability in the wind farm and maximize limited impact from the voltage fluctuation of the voltage Control Bus to maintain voltage stability of local grid.

  • optimal design of a wide area measurement system for improvement of power network monitoring using a dynamic multiobjective shortest path algorithm
    IEEE Systems Journal, 2017
    Co-Authors: Amir Ghasemkhani, Hassan Monsef, Ashkan Rahimikian, Amjad Anvarimoghaddam
    Abstract:

    Wide area measurement system (WAMS) usually contains three dependent infrastructures called management, measurement, and communication. For optimal operation of a power system, it is necessary to design these infrastructures suitably. In this paper, measurement and communication infrastructures in a wide area network are designed independently from a management viewpoint, considering an adequate level of system observability. In the first step, optimal placement of measurement devices is determined using an integer linear programming (ILP) solution methodology while taking into account zero-injection Bus effects. In the next step, new dynamic multiobjective shortest path (MOSP) programming is presented for the optimal design of communication infrastructure. The best architecture design is introduced in terms of optical fiber power ground wire (OPGW) coverage for the suggested central Control Bus and the number of phasor measurement units (PMUs). The applicability of the proposed model is finally examined on several IEEE standard test systems. The simulation results show better performance of the proposed method compared with other conventional methods. The numerical results reveal that applying the proposed method could not only reduce the OPGW coverage cost, the number of PMUs, and the number of communication links but could also improve the system technical indexes such as latency as subsidiary results of the optimization process.
