Od viškov sončne energije do tople vode izvedba zaprtozančne regulacije balkonske elektrarne From excess solar energy to hot water Balcony solar power plants represent an increasingly popular solution for local energy generation in households due to their simple installation and low investment costs. However, without battery storage, significant energy surpluses occur during peak production hours, which are typically injected into the grid for free or lost due to inverter power limiting. This paper presents the design and real-world implementation of a closed-loop control system that utilizes an existing domestic electric water heater as a dynamic thermal energy storage unit. By acquiring real-time power data directly from the smart meter’s P1 port using an ESP32-C3 microcontroller, the control algorithm continuously modulates the heater’s power via a phase-angle regulator to minimize grid export. The paper analyzes the thermal model of the boiler, the linearisation of the dimmer characteristic, and evaluates the robust control strategy designed to handle grid voltage fluctuations, measurement noise, and fluctuating household loads. vtična sončna elektrarna zaprtozančno vodenje zalogovnik toplotne energije balcony solar plant closed-loop control thermal energy storage true false true Slovenski jezik Angleški jezik Neznano 2026-11-05 12:18:19 2026-11-05 12:18:22 2026-11-06 04:29:37 0000-00-00 00:00:00 2026 0 0 Str. 221-224 0000-00-00 NiDoloceno Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.311.243:681.5 2591-0442 293113859 292311811 RAZ_Klancar_Gregor_2026.pdf RAZ_Klancar_Gregor_2026.pdf 1 9EAECA18E1E0BCFCE1723FEB156ECFD6 90fd1c3977bd2a496b6ac76ff5d6ef17d4abc2d06374ff32c48588b1100e0575 892b04c3-d90a-11f1-aea2-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=252546 https://erk.fe.uni-lj.si/2026/papers/klancar(od_viskov).pdf 0 b341b7bd-d90a-11f1-aea2-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=252549 Fakulteta za elektrotehniko 0 0 0
