“…From the obtained results the viability and profitability of the NEM policy in the nine campuses is evaluated and the optimal size for the PV system is determined in terms of maximizing the net present value by applying an exhaustive search optimization procedure. The present work extends a previous study [32] that has described preliminary investigations. Additional strengths and contributions of the analysis are:  Unlike most relevant methods, the proposed methodology combines techno-economic analysis (in terms of several indicators) with quasi-static simulations to incorporate the real-world operational properties of the distribution network; thus, improving the accuracy of the final evaluation.…”

“…The public power corporation (PPC) S.A. is the current major electricity supplier in Greece and offers different electricity tariffs, depending on the MV customer type. For large MV customers, e.g., commercial, industrial, campuses etc., the PPC offers specific reduced electricity pricing charged on monthly basis [32]. The total electricity tariff (Ctot) is subdivided into supply charges (Csupply), regulated charges (Cregulated) and municipal fees and taxes (Cmunicipal):…”

“…The economic viability of the NEM policy regarding low-voltage (LV) residential prosumers has been well investigated in several studies [4], [7], [8], [10], [27] - [31]. However, according to the authors' knowledge there are very few relevant works regarding MV prosumers [32]. In particular, LV prosumers are charged with volumetric retail rates based on the total consumed energy (in terms of real power), assuming unity power factor (typically the case for most households) [5].…”

Net-metering has been introduced as an alternative to the feed-in tariff scheme to encourage consumers to act as prosumers by installing photovoltaics. Originally, net-metering referred mainly to household photovoltaic systems, however, larger prosumers connected to medium-voltage networks are also considered. Scope of this paper is to present a techno-economic assessment methodology to evaluate the viability of net-metering policy in medium-voltage prosumers. Unlike most relevant methods, the proposed methodology combines techno-economic analysis with a quasi-static simulation model incorporating the real-world operational properties of the distribution network, where the medium-voltage prosumers are connected. The analysis focuses on nine university campuses operating under net-metering policy. The impact of several important parameters on the viability of the investment as well as on the optimal size of the system is investigated; among them special emphasis is given on the applicability of the decentralized voltage regulation techniques applied to the prosumer's photovoltaic system.
