Conferences > 2023 6th International Confer... Multi-energy complementary microgrid systems can take advantage of the characteristics of various types of energy sources, improve energy utilization efficiency, increase economic benefits, reduce the cost of electricity, and reduce carbon emissions.
To demonstrate the feasibility of the proposed optimization method and multi-energy complementary distributed energy system, three optimal configuration schemes (S1, S2, and S3) are obtained and compared by the single objective optimization, in which the key indicators used are the objective of ATC, ATCE, and ATFC, respectively.
The candidate technologies are grouped into five subsystems: electricity subsystem, solar thermochemical methane steam reforming (STCMSR) subsystem, solid oxide fuel cell subsystem, cooling subsystem, and thermal integration subsystem. Fig. 4. The structure of the multi-energy complementary distributed energy system.
The developments of energy storage and multi-energy complementary technologies can solve this problem of solar energy to a certain degree. The multi-energy hybrid power systems using solar energy can be generally grouped in three categories, which are solar-fossil, solar-renewable and solar-nuclear energy hybrid systems.
The energy storage sub-system is also usually necessary for solar and nuclear energy hybrid systems. Solar energy sub-system can be chosen to employ either PV or solar thermal technology, and nuclear energy sub-system is always a reactor.
The European energy storage market is booming with Germany leading residential adoption (+58% YoY) thanks to €500/kWh subsidies. Italy's new tax credits drive 5.2GWh commercial deployments, while UK grid-scale projects exceed 8GWh with 2-hour duration systems. Key selection criteria: German-certified safety (VDE-AR-E 2510), 10+ year warranties, and VPP readiness. Top-performing products include Sonnen's hybrid inverters (98% efficiency) and BYD's Blade Battery (12,000 cycles @80% DoD). For snowy regions like Scandinavia, consider Huawei's -30°C compatible systems. France mandates carbon footprint declarations - Sungrow's ISO-14067 certified solutions gain preference.
For European homeowners, 5-10kWh systems with 3-phase compatibility are ideal. Top picks: 1) Tesla Powerwall 3 (13.5kWh, 97% round-trip efficiency) for smart home integration; 2) LG Chem RESU Prime for compact urban installations; 3) SMA Sunny Boy Storage for retrofit projects. Critical features: EU-made battery cells (exempt from CBAM tariffs), dynamic tariff optimization (like Octopus Energy integration), and fire-safe LiFePO4 chemistry. Southern Europe demands 85%+ depth of discharge capability, while Nordic markets require -25°C operation. Always verify CEI 0-21 compliance for Italian grid connection and EnWG certification for German feed-in.
