1. mga Hamon
1.1 Hindi Sapat na Pagsasamantala sa Dalawang Direksyon ng Pagdaloy ng Kuryente
Ang dalawang direksyon ng pagdaloy ng kuryente ay nagpapahina ng estabilidad ng voltaje at nagdudulot ng overload sa mga aparato, nanganganib ang mga transformer at integridad ng grid. Kinakailangan ng pinahusay na disenyo ng adaptasyon.
Ang tradisyonal na 10 kV distribution transformers, na disenyo para sa unidireksyonal na pagdaloy ng kuryente, ay may hirap na acommodate ang integration ng distributed generation sa microgrids.
Ang optimisadong disenyo ng transformer ay nagpapabuti ng pagsasamantala sa dalawang direksyon ng pagdaloy ng kuryente, tiyak na nagbibigay ng matatag na suplay ng kuryente at pinahahabang buhay ng mga aparato.
1.2 Mga Hamon sa Kontrol ng Kalidad ng Kuryente
Ang mga microgrid ay nakakaharap sa intermitenteng renewable generation at harmonic pollution mula sa power electronics, na nagbabanta sa estabilidad ng voltaje/frequency.
Ang mahalagang kapaligiran ng kuryente ay nagpapabilis ng mga nawalan ng transformer at lokal na sobrang init, na nagdudulot ng pagtanda ng insulation at panganib ng fault.
Ang advanced na mitigasyon ng kalidad ng kuryente ay nagbabawas ng mga nawalan at fault ng transformer, tiyak na nagbibigay ng mas ligtas na operasyon ng microgrid.
1.3 Masamang Komunikasyon & Koordinasyon ng Kontrol
Ang umiiral na 10 kV transformers ay kulang sa robust na communication interfaces para sa integration ng microgrid energy management system (EMS).
Ang limitadong interoperability ay naghahadlang sa flexible dispatch at optimal na operasyon ng microgrid.
Ang smart transformer upgrades na may IoT-enabled communication protocols (halimbawa, IEC 61850) ay kritikal para sa controllability sa grid-edge.
1.4 Hindi Sapat na Konfigurasyon ng Proteksyon
Ang tradisyonal na mga scheme ng proteksyon ay hindi nag-aaddress sa pagbabago ng direksyon ng fault current dahil sa distributed energy resources (DERs).
Ang dalawang direksyon ng pagdaloy ng kuryente ay nagkomplica sa coordination ng overcurrent/earth fault protection, nagdudulot ng dagdag na panganib ng misoperation.
Ang directional overcurrent relays at synchrophasor-based algorithms ay kinakailangan para sa fault isolation sa hybrid grids.
