This paper describes a power system inertia estimation method that utilizes perturbations caused by the flow switch on an HVDC interconnector. The analysis is performed using real measurements from Ireland's all-island system. employs energy based technique which permits non-step change to be used for calculation and encapsulates challenges associated with use of data. While it shown synchronou...

Since the limited power capacity, finite inertia, and dynamic loads make the shipboard power system (SPS) vulnerable, the automatic reconfiguration for failure recovery in SPS is an extremely significant but still challenging problem. It is not only required to operate accurately and optimally, but also to satisfy operating constraints. In this paper, we consider the reconfiguration optimizatio...

in this paper, the development and optimization of power distribution control strategy (pdcs) have been performed for a hybrid energy storage systems (hess) of a series hybrid electric bus (sheb). a common pdcs is based on the use of ultra-capacitor (uc) pack. a new simple pdcs is developed as a battery based one. for the battery based pdcs, four parameters are introduced for tuning the pdcs pe...

Power system inertia typically refers to the energy stored in large rotating synchronous generators. Dynamics and stability of traditional power is closely linked natural these In recent years, increasing amount generators have been replaced by high different type inverter-based generating units connected at voltage levels system. Therefore, dynamics future low-inertia systems will be increasin...

Reliability investigation has always been one of the most important issues in power systems planning. The outages rate in power system reflects the fact that more attentions should be paid on reliability indices to supply consumers with uninterrupted power. Using reliability indices in economic dispatch problem may lead to the system load demand with high reliability and low probability of powe...

In this paper, a hybrid solid oxide fuel cell (SOFC) and micro gas turbine (MGT) power system is parametrically studied to evaluate the effect of different operating conditions. The SOFC/MGT power system includes SOFC reactor, combustion chamber, compressor and turbine units, and two heat exchangers. The effects of fuel utilization, temperature, and pressure are assessed on performance of t...

Energy storage systems are recognised as the potential solution to alleviate impacts of reduced inertia and intermittency in power due integration renewable energy sources. Several technologies available market with diverse characteristics, operational limitations, costs. Besides, frequency regulations have different requirements, for example, inertial response requires high a short period whil...
