Plug-in electric vehicles (PEVs) present environmental and energy security advantages versus conventional gasoline vehicles. In the near future, number of plug-in will likely grow significantly in world. Despite aforementioned advantages, connection PEV to power grid poses a series new challenges for utilities. This paper proposes comprehensive approach evaluating impact different levels penetration on distribution network investment incremental losses. The proposed is based use large-scale...
The penetration level of plug-in electric vehicles (PEVs) has the potential to be notably increased in near future, and as a consequence, power systems face new challenges opportunities. In particular, PEVs are able provide different types system ancillary services. capability storing energy instantaneous active control fast-switching converters two attractive features that enable various services, e.g., primary frequency (PFC). However, concurrently, obliged operated controlled within...
This paper describes a novel strategy to design the frequency-droop controller of plug in electric vehicles (PEVs) for primary frequency control (PFC). To be able properly compare response system with and without PEVs, is done guarantee same stability margin both systems worst case scenario. identify case, sensitivity analyses are conducted on large set parameters performing eigenvalue analysis bode plots. Three main contributions included this work: 1) we demonstrate that PEVs using...
In the future, number of plug-in electric vehicles (PEVs) that will participate in primary frequency control (PFC) is likely to increase. our previous research, computational complexity PFC problem for a large PEVs was reduced using aggregate models PEVs. However, literature on PFC, distribution network characteristics have not been included despite fact be dispersedly connected network. This paper proposes an model further incorporates characteristics, i.e., power loss (DNPL) and maximum...
The increasing deployment of non‐dispatchable generation in electric systems where and demand must be balanced at all times has led to a renewed interest technologies for energy storage. This study presents cost–benefit analysis storage peak reduction medium‐voltage distribution networks. In particular, the installation batteries secondary substations is studied three realistic large‐scale networks representing urban, semi‐urban rural areas. On one hand, savings costs derived from storing...
Abstract Nowadays, the amount of distributed generation (DG) connected to distribution networks is increasing significantly. In a European context, one main drivers for this growth support electricity from renewable energy sources (RES) and combined heat power (CHP) plants. Hence, these DG units mostly consist non‐controllable generation. Distribution regulated activity which is, at least, legally functionally unbundled activity. These issues, together with fact that were not originally...
This paper presents a novel ground-fault-detection technique for synchronous machines. is suitable machines with static excitation systems, whose field winding fed by rectifiers through an transformer. The main contribution of this new that it can detect and discriminate both ac- dc-side ground faults in the system, without need traditional power injection sources. detection based on frequency analysis voltages or currents at grounding impedance placed transformer neutral terminal. has been...
This paper presents a novel on-line rotor ground fault location method for synchronous machines, which, combined with protection, can detect and locate faults in the rotor. is suitable machines static excitation systems, whose field winding fed by rectifiers through an transformer. The main contribution of this new technique that it position online, reducing repair time. proposed based on analysis ac dc components voltage measured grounding resistance located neutral terminal has been...
Frequency response analysis (FRA) is a very common test for the diagnosis of power transformers. This paper presents some relevant results on application FRA to rotating machines. First, reference rotor position obtaining machine proposed. Then, with proposed used identify faults in stator machine. studies turn-to-turn and ground different fault resistance values. Several laboratory tests demonstrate applicability value use
Advanced metering infrastructures (AMIs) represent one of the first steps in smart grid process, where power line communication (PLC) is emerging as most cost-effective solution since it allows reusing electric channel. However, performance this technology highly affected by characteristics existing distribution network. This paper presents a thorough sensitivity analysis to assess operating limits applications for multiple representative configurations low voltage networks based on PLC...
