“…DGs offer many advantages, including the generation of power close to the point of consumption. However, grid-connected distributed generators providing reverse power flow will cause changes to the power grid [101]: DG characterization is the qualification and quantification of the behavior of grid-connected inverters to increase system stability. Online monitoring of the active and reactive power of DGs enables responses to abnormal situations.…”

Synchrophasor technology opens a new window for power system observability. Phasor measurement units (PMUs) are able to provide synchronized and accurate data such as frequency, voltage and current phasors, vibration, and temperature for power systems. Thus, the utilization of PMUs has become quite important in the fast monitoring, protection, and even the control of new and complicated distribution systems. However, data quality and communication are the main concerns for synchrophasor applications. This study presents a comprehensive survey on wide-area monitoring systems (WAMSs), PMUs, data quality, and communication requirements for the main applications of PMUs in a modern and smart distribution system with a variety of energy resources and loads. In addition, the main challenges for PMU applications as well as opportunities for the future use of this intelligent device in distribution systems will be presented in this paper.

“…The effect on losses is not selfevident and distributed generation can in fact decrease distribution losses since the power is generated closer to the consumer. 37 The manual battery dispatch model in the SAM is used to add a battery to the system. 33 PV generation is rst used to directly meet the residential load, secondly charges the battery, and thirdly exports power to the grid.…”

“…The resources used in distributed generation are renewable energy sources and cogeneration i.e., production of heat and electricity simultaneously. DGs are having some advantageous characteristics like free location in the network area, relatively small generated power, increased reliability of the Grid, reduced transmission and distribution line losses, better voltage support and power quality improvement [1]. The backup (standby) generation, utility grid enhancement, peak shaving, load management etc are the various applications of distributed generation.…”

Distributed generation is significantly gaining attention due to increase in the electricity demand. Distributed generations are mostly used with the association of power distribution systems to energize local loads and network. Islanding is technically an undesirable condition which demands necessary steps to reduce negative effects which helps in maintaining stability of the system. In the present work, alienation technique has been applied to detect and differentiate islanding, and sudden load change. A radial system with four Distributed Generations (DFIG wind generator) connected to the source through common coupling point (PCC) has been used for comprehensive study of this technique. The current signals were decomposed with Daubechies (db1) wavelet to obtain approximate coefficients at each bus. The approximate wavelet coefficient over a moving window of half cycle was used to compute alienation coefficients. The alienation coefficients were used to compute Islanding index and fault index. The same indices were compared with threshold to differentiate Islanding and sudden load change. The proposed algorithm has been tested for various incidence angles for both islanding condition and faults. This technique is found to be robust, effective to detect islanding condition and impact of sudden load change.
