In this paper, the performances of three voltage control strategies for DC microgrids are compared, including the proportion integration (PI) control, the fuzzy PI control and particle swarm optimization (PSO) PI control.
A DC microgrid voltage stabilization control strategy is designed based on droop control and improved PI control, which effectively improves the stability of DC microgrid operation. The simulation model of a DC microgrid system with composite energy storage is built on a simulation platform.
An effective control strategy should be employed for a DC microgrid system's well-organized operation and stability. Converters are critical components in the operation of DG microgrids as they ensure proper load sharing and harmonized interconnections between different units of DC microgrid.
DC Microgrid (MG) with DC distribution system is an attractive technology over the last decade due to its inherent compatibility with renewable energy sources (RESs), DC loads, and storage devices.

Compared with AC microgrids, DC microgrids have no problems in reactive power, phase and frequency, and DC voltage has become an important indicator of system stability [ 3 ]. In DC microgrid system, in order to ensure the stability of DC voltage, it is necessary to coordinate the control of multiple microsources.
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.
