The region-based method has been applied in transmission systems and traditional passive distribution without power sources. This paper proposes the model of total quadrant security region (TQSR) for active networks (ADN) with high penetration distributed generation (DG). Firstly, TQSR is defined as a closed set all N-1 secure operation points state space ADN. Then, modeled considering constrai...

Distributed power generation-electricity generation that is produced by many small stationary power generators distributed throughout an urban air basin-has the potential to supply a significant portion of electricity in future years. As a result, distributed generation may lead to increased pollutant emissions within an urban air basin, which could adversely affect air quality. However, the us...

The occurrence of distortion and over voltage at the Point Common Coupling (PCC) Renewable Distributed Generation (RDG) limits its penetration levels to power system RDG integration is expected play a crucial role in transformation. For penetrations be sustained without disconnection from system, there must solution rise, distortion, unbalanced current grid reactive control strategy PCC. It an ...

Y our jaw will drop when you see how the " tech surge " team fixed HealthCare.gov! Well, okay, now that I've got your click, I'll open with the lead that HealthCare.gov didn't really get fixed. And it's even worse than it appeared. Here's the story from my good friend Robert Kennedy, who was part of the team that made this critical, Web-based registration service work well enough that the enrol...

This study proposes an evaluation method for variable generation (VG) acceptability with an adequate level of power system flexibility. In this method, a risk index referred to as the ramping capability shortage expectation (RSE) is used to quantify flexibility. The RSE value of the current power system is selected as the adequate level of flexibility (i.e., RSE criterion). VG acceptability is ...

the iranian ministry of energy commands the regional electrical companies to install dg resources at 63kv/20kv substations and at the end of 20kv lines. the first and foremost challenge in installing these resources is deciding on the optimal place and capacity of these resources. this paper is aimed to propose an appropriate algorithm for siting and sizing such resources in bakhtar regional el...
