Power and Energy Systems Department (ZVNE), Power and Energy Chapter (PES) and IEEE Croatia section invite you to the lecture:

"Photovoltaics (PV) hosting capacity of low voltage distribution system considering uncertainties"

given by Arpan Koaira, PhD, researcher from Electrical Energy Systems and Applications (ELECTA) department, KU Leuven, Belgium.

The lecture will be held on Thursday, 13 April 2023, from 5 PM in Grey Hall (Siva Vijećnica) at the Faculty of Electrical Engineering and Computing, Unska 3, Zagreb.

The total duration of the lecture is 60 minutes and will be held in the English language. The lecture is open to everyone interested, and we especially invite colleagues from the University, students, researchers and industry partners to join the discussion on this exciting theme.

The lecture abstract and CV of the lecturer can be found below in the extended invitation.

Arpan Koirala (Student Member, IEEE) received the master's degree under the Erasmus Mundus Master Course in Sustainable Transportation and Electrical Power Systems from the consortium of the University of Oviedo, Gijón, Spain, La Sapienza, Rome, Italy, University of Nottingham, Nottingham, U.K., and Polytechnic Institute of Coimbra, Coimbra, Portugal, in 2018. In 2023, he obtained his PhD, from KU Leuven, Belgium. His research interests include stochastic programming, optimization, distribution system modelling, energy market, and high-scale integration of renewable resources.

Abstract:

The increased penetration of renewable resources, such as photovoltaics (PV) and new loads, such as electric vehicles (EV) and heat pumps (HP), have increased uncertainty levels in the low voltage distribution system (LVDS). The traditional approach to planning such LVDS is the conservative "fit and forget" approach investing for the worst-case scenario, which means installing a lot of additional infrastructure. However, considering LVDS planning as a stochastic problem is deemed more efficient, reducing grid infrastructure investment costs. Determining the PV hosting capacity (HC) is one such planning problem, yielding the capacity of the system to incorporate new PV resources. Stochastic HC calculations are currently done using computationally expensive, iterative Monte Carlo (MC) based methods, which require solving the power flow equations thousands of times for each iteration of the PV installation scenario. To calculate the PV HC of a large service area consisting of thousands of LV feeders, a computationally tractable and accurate probabilistic power flow (PPF) tool is required. Various approaches exist to make the MC-based iterative HC calculation method computationally more efficient, e.g., linearizing the power flow equations, replacing some of the uncertain variables with deterministic values, etc. Alternatively, MC-based methods can be replaced by faster analytic methods, or the iterative HC calculation method can be replaced by stochastic optimization. In this talk, various approaches to calculating PV HC of LVDS considering uncertainties will be discussed.
