Power System

In this video we will show how to perform power flow analysis with holomorphic embedding load flow method (HELM). HELM is a robust method that can univocally yield the high voltage solution to the power flow equation, whenever such a solution exists. — Motivation for HELM As we have shown in the first part of the series, one of the feature and also the main problem in power flow analysis is that the power flow equation

Q1. How to choose the right circuit breaker based on the trip time-current curves? In order to balance the right amount of overcurrent protection against optimal machine operation, we need different trip curves. Selecting a circuit breaker with a trip curve that trips too soon can result in nuisance tripping…

The Levelized Cost of Electricity (LCOE) is a metric used to compare the costs of a power plant project to the electricity that it will generate. …

How do we make sure the power system operates in a safe, efficient and stable way — and get electricity to where it’s needed on the grid — Ancillary services are the name we give a range of measures that make sure our power system provides enough electricity where it is needed, but also keeps it stable. We always need to maintain a balance between the amount of electricity that’s being generated, and the amount that’s being used.

In this and the following videos, we will talk about power flow analysis. It is one of the most important and fundamental area of science when we want to examine whether a power system can be operated in a safe and stable manner. — But first we need to know what it is, why it is important, and what it usually can or cannot do. Then we will dig into the physics and math of the theory behind. In the later videos, we will then discuss methods to actually conduct a power flow analysis.
