“…That's why weight indicators for each grid have to be adjusted. To overcome the problems above [17][18][19], method of minimizing losses of power and overtime tension deviation in MM with the distributed generation is offered. This method provides the use of results of math modeling according the genetic algorithm of non-dominant sorting (NSGA).…”

“…In the absence of any communication infrastructure using OLTC may not be sufficient to control the voltage level and reactive power [28]. With the support of communication networks, reactive power can be controlled remotely using a capacitor bank at the local control center [7]- [10]. Within the centralized scenario, if the synchrophasor information throughout the distributed feeder is made available at the DNO, the controller would then be able to instruct power injection from generators/inverters that are nearest to the loads with high demand by analyzing the data in each local area.…”

There has been a growing interest in the deployment of Phasor Measurement Units (PMUs) in a Distributed Generation (DG) grid system. A major obstacle is the lack of a communication network infrastructure that can support phasor measurements for distribution area monitoring as well as providing sensing capabilities for protection against undesirable grid dynamics. In the absence of such a network, the most costeffective solution would be to consider a wireless network to support centralized control for situational awareness in a DG environment. Therefore, the main objective in this paper is to design and implement a synchrophasor network testbed using Wireless LAN (WLAN) technology. Based on a hierarchical network architecture, we propose an efficient method to reduce the synchrophasor data bandwidth, as well as provide capabilities for control and management at each hierarchical level. This testbed is then used to evaluate different network configurations under various test conditions.

“…However, their deployment in a distribution system faces many obstacles, such as insufficient phasor measurement accuracies under noise and harmonics. In addition, the presence of volt-ampere-reactive (VAR) power can create serious instabilities due to the presence of nonlinear loads [32]–[36]. Because PMUs measure voltage and current phasors, they can directly compute real power and VAR flows at precise moments in time.…”

This paper focuses primarily on leveraging synchronized current/voltage amplitudes and phase angle measurements to foster new categories of applications, such as improving the effectiveness of grid protection and minimizing outage duration for distributed grid systems. The motivation for such an application arises from the fact that with the support of communication, synchronized measurements from multiple sites in a grid network can greatly enhance the accuracy and timeliness of identifying the source of instabilities. The paper first provides an overview of synchrophasor networks and then presents techniques for power quality assessment, including fault detection and protection. To achieve this we present a new synchrophasor data partitioning scheme that is based on the formation of a joint space and time observation vector. Since communication is an integral part of synchrophasor networks, the newly adopted wireless standard for machine-to-machine (M2M) communication, known as IEEE 802.11ah, has been investigated. The paper also presents a novel implementation of a hardware in the loop testbed for real-time performance evaluation. The purpose is to illustrate the use of both hardware and software tools to verify the performance of synchrophasor networks under more realistic environments. The testbed is a combination of grid network modeling, and an Emulab-based communication network. The combined grid and communication network is then used to assess power quality for fault detection and location using the IEEE 39-bus and 390-bus systems.
