Aqlli shahar elektr tarmoqlarida qayta tiklanuvchi energiya manbalarining, xususan, fotovoltaik qurilmalarning keng integratsiyalashuvi elektr tarmog‘ining kuchlanish rejimi, quvvat oqimlari va energiya yo‘qotishlariga ta’sir ko‘rsatadi. Taqsimlangan generatsiyasining o‘zgaruvchanligi hamda iste’mol yuklamasining dinamik xarakteri ushbu jarayonlarni muvofiqlashtirilgan boshqarishni talab etadi. Mazkur tadqiqotda PV qurilmasi va akkumulyator energiya saqlash tizimini (BESS) birgalikda boshqarishga asoslangan takomillashtirilgan PSO–MPC usuli taklif etiladi. Boshqaruv jarayonida aktiv quvvat yo‘qotishlari, kuchlanish og‘ishi, tarmoqdan olinadigan quvvat va BESSning ish holati yagona ko‘p mezonli optimallashtirish funksiyasida hisobga olinadi. Tadqiqot IEEE 33-tugunli radial taqsimlash tarmog‘i asosida olib borildi. Modellashtirish natijalariga ko‘ra, taklif etilgan boshqaruv usulida aktiv quvvat yo‘qotishlari 210,9 kVt dan 92,4 kVt gacha, minimal kuchlanish esa 0,913 p.u. dan 0,968 p.u. gacha yaxshilandi. Olingan natijalar PV va BESSni muvofiqlashtirilgan boshqarish tarmoqning energetik samaradorligi va kuchlanish rejimini yaxshilash imkonini berishini ko‘rsatadi.
