© 2021 IEEE.This paper presents a prediction of customer-based reliability indices, System Average Interruption Frequency Index (SAIFI), System Average Interruption Duration Index (SAIDI), and Energy Not Supplied (ENS) for two different cases and compare those cases. In the first case, whole loads are fed through the distribution network, whereas the rooftop PV generation integrated into the grid and transactive energy market has been considered in the second case. Pricing the prosumers' strategies is based on the Turkey electricity market conditions and realistic future estimates of the national grid. Moreover, sunlight durations are also considered for the reliability assessments in the second case. In this regard, the rooftop PV system's average output for an average spring/autumn day is considered. Simulations are performed for the European LV test feeder, where the irradiation data is provided from a Turkish district.
