ENGLISH ABSTRACT: This research investigates the technical impacts of energy storage systems (ESSs) on low voltage (LV) residential feeders. A critical literature review on the existing impact assessment methodologies informs on the requirements of an efficient methodology that ensures the accurate and detailed assessment of feeder performance under ESS penetration. Based on the review’s findings, a comprehensive stochastic-probabilistic methodology is proposed that directly accounts for the unpredictability in customer behaviour and the subsequent impact on the diversity and variability in simulation inputs and outcomes of load flow analysis (something that most impact assessment methodologies do not adequately account for). The proposed methodology makes use of the Monte Carlo Simulation method as a stochastic simulator to simulate the uncertainty in the feeder placement of ESSs, and the Herman-Beta extended algorithm to solve the probabilistic load flow analysis. This proposed methodology can be used to assess the hosting capacity of radial LV distribution feeders to increasing penetrations of ESSs. The simulation results, from detailed and comprehensive input modelling, can provide helpful and more accurate and representative information to distribution network planners and policymakers, than simplified methodologies. AFRIKAANSE OPSOMMING: Hierdie navorsing ondersoek die tegniese gevolge van energieopbergings stelsels (EOS) op lae spanning (LS) residensiële toevoere. 'n Omvattende literatuuroorsig van bestaande impakbeoordelingsmetodologieë gee inligting oor die vereistes van 'n doeltreffende metodologie wat die akkurate en gedetailleerde assessering van die voerprestasie onder ESS-penetrasie verseker. Op grond van die oorsig bevindings, word 'n omvattende stogastiese-waarskynlikheids metodologie voorgestel wat die onvoorspelbaarheid van kliëntegedrag aanspreek en die impak op diversiteit en wisselvalligheid in simulasie-insette en simulasie-uitkomste van lasvloei-analise (iets wat die meeste impakassesseringsmetodologieë nie voldoende aanspreek nie). Die voorgestelde metodologie maak gebruik van die Monte Carlo Simulasie metode as ‘n stogastiese simulator om die onskerheid in toevoerplasing van die ESS te simuleer, en die Herman-Beta- uitgebreide algoritme om die waarskynlike lasvloei-analise op te los. Hierdie voorgestelde metologie kan gebruik word om die huisves kapasiteit van die radiale LV-verspreidingstoevoere te beoordeel met betrekking tot toenemende penetrasies van ESS's. Hierdie simulasie-resultate, van gedetailleerde en omvattende insetmodellering, kan nuttige, meer akkurate en verteenwoordigende inligting aan verspreidingsnetwerkbeplanners en beleidsmakers bied as vereenvoudigde metodologieë.
