Introduction to Microgrids | Microgrid System Development and Analysis, Part 1
From the series: Microgrid System Development and Analysis
In this first video on microgrids, the concept of distributed power systems is introduced. While the focus of this series will be on microgrids, the concepts discussed on distributed power and energy resources are for other applications, such as more electric aircraft and ship electrification.
Traditional utility transmission and distribution rely on centralized generation from conventional power plants. The increase in availability of distributed energy resources (DERs) on distribution feeders has led to an interest in a paradigm shift. One such proposed approach is the microgrid. The microgrid can be interconnected with the utility grid through a point-of-common coupling (PCC) or it can choose to “island” to remain online if weather or grid faults occur. Microgrid islanding with local DERs allow a drastic increase in reliability. Additionally, microgrids could be completely isolated in remote areas without traditional utility access.
With the addition of a supervisory microgrid controller, additional renewable DERs and energy storage resources can be integrated into the grid effectively. As is also introduced in this video, validation and testing of controllers is essential prior to grid integration. MathWorks tools can enable both microgrid control design, testing, and implementation on the final control hardware.

Microgrid: Maendeleo na Uchambuzi wa Mfumo wa Microgrid (Makundi ya Microgrid) ni mkusanyiko wa video za microgrid ambazo zinaonyesha mifumo ya umeme iliyosambazwa. Ingawa lengo la mfululizo huu itakuwa juu ya microgrids, dhana zilizozungumziwa juu ya usambazaji wa nguvu na rasilimali za nishati ni kwa matumizi mengine, kama vile ndege zaidi za umeme na umeme wa meli. Mawasiliano ya jadi ya huduma na usambazaji hutegemea uzalishaji wa kati kutoka kwa mitambo ya umeme ya kawaida. Kuongezeka kwa upatikanaji wa rasilimali za nishati za usambazaji (DERs) kwenye feeder za usambazaji kumesababisha maslahi katika mabadiliko ya mfano. Njia moja inayopendekezwa ni ile ya kutumia mtandao mdogo wa umeme. Microgrid inaweza kuunganishwa na gridi ya huduma kupitia kuunganisha kwa kawaida (PCC) au inaweza kuchagua "kisiwa" kubaki mtandaoni ikiwa hali ya hewa au makosa ya gridi yanatokea. Microgrid kisiwa na DERs za mitaa kuruhusu ongezeko kubwa katika kuegemea. Kwa kuongezea, microgrids inaweza kutengwa kabisa katika maeneo ya mbali bila upatikanaji wa huduma ya jadi. Kwa kuongeza udhibiti wa microgrid ya usimamizi, DERs za ziada za upya na rasilimali za kuhifadhi nishati zinaweza kuunganishwa kwenye gridi kwa ufanisi. Kama pia ni kuletwa katika video hii, uthibitisho na kupima controllers ni muhimu kabla ya grid ushirikiano. MathWorks zana inaweza kuwezesha wote microgrid kudhibiti kubuni, kupima, na utekelezaji juu ya mwisho kudhibiti vifaa. Unaweza pia kuchagua tovuti kutoka orodha ifuatayo: Jinsi ya kupata utendaji bora wa tovuti Chagua tovuti ya China (kwa Kichina au Kiingereza) kwa utendaji bora wa tovuti. Tovuti nyingine za nchi za MathWorks hazijaendelezwa kwa ziara kutoka eneo lako.
