要約(日本語): The control of power system elements, treated as passive loads or generators traditionally, is becoming an important operational aspect in future ubiquitous power networks. Among the elements considered for control are heat pumps, battery storage, distributed energy resources and feeders from main grid. These elements, large in numbers, and are connected to the power network at distribution level and customer premises. In future power networks more communication services and control functions in the form of coordinated control are expected to appear as a result of utilities’ efforts to make power networks smarter. The authors have been working on an algorithm that has the potential to support the coordinated control requirements of future power systems. Based on the objective of maximizing energy harnessed form renewable sources without causing major fluctuation in power flows within the system, this algorithm, through computer simulations, was proven to be capable of coordinating various controllable elements in power systems effectively. However studies carried out so far were limited to the cases in which the energy capacities of customer loads were not considered as a constraint. With heat pumps gaining popularity as a controllable load, the energy capacity limitations of them are introducing hard constraints to coordinated control problem. In this paper the authors present the outcomes of simulations carried out by them using their algorithm while taking energy limit constraint of customer loads into account. The simulation outcomes illustrate that under energy capacity limitations also, the proposed algorithm can produce satisfactory results.
