PLANNING OF A SELF-SUFFICIENT ENERGY SYSTEM WITH 100% RENEWABLE ENERGY SOURCES AND HYDROGEN STORAGE
KOMUNALNA ENERGETIKA / POWER ENGINERING, 17
A potential solution for stand-alone power generation is to use a hybrid energy systems with hydrogen energy storage. In this paper, a pre-feasibility study of using 100% renewable hybrid energy system (using solar and wind energy source) with hydrogen technologies (electroyser, hydrogen tank, fuel cell) for a reference household application in Portorož, Slovenia is explained. HOMER software tool is used for simulations and optimal energy system determination, where geographical location and availability of energy sources, load dynamics, component technical and economical characteristics were considered. A remote household with electricity consumption of 11 kWh/day with a 3,8 kW peak power demand was considered as the stand alone load. Results show the optimal feasible system with lowest total net present cost. It was found that almost a ten-fold (34 kW) renewable technology capacity is required to meet the demand.

PLANNING OF A SELF-SUFFICIENT ENERGY SYSTEM WITH INTERNAL COMBUSTION ENGINE
KOMUNALNA ENERGETIKA / POWER ENGINERING, 9
The paper presents method of optimization of a self-sufficient energy system configuration. At the beginning an optimisation method for advanced planning of energy supply systems is presented. Secondly, Mathwork’s Simulink was used to describe dynamic mathematical model consisting of energy user, energy production unit (internal combustion engine - ICE), energy saving capacities (battery) and regulation. At the end optimal system was found through a series of simulations which ensures stable and rational energy supply with respect to different rules of operation, particular sub-system’s sizes and economical aspects. At the end, results, appropriate diagrams and future guidelines are shown.
