16 Νοε 2021 · In order to enable durable and economically viable use by integrating DC and AC DERs into microgrids, hybrid AC/DC microgrids (HMGs-AC/DC) present one of the most promising approaches in eliminating the need for AC-DC or DC-AC conversions.
The investment cost, operation and maintenance cost, replacement cost, etc., have been considered in the life cycle cost analysis. Power losses of both the AC and DC section are calculated with an open source simulation tool, the Open Distribution Simulator Software (OpenDSS).
12 Σεπ 2019 · This paper first summarizes the physical characteristics and morphological evolution of AC-DC hybrid DER system. The impact of these new features on system configuration planning is analyzed with respect to its flexible networking, rich operation control modes, and tight source-network-load-storage coupling.
1 Φεβ 2020 · The proposed model determines the optimal AC-DC network configuration that achieves two main objectives: (1) minimizing system costs, and (2) maximizing system reliability.
24 Ιαν 2019 · With DC coupling, the price of the large-battery system is $45,237, which is $17,534 (63%) higher than the small-battery system. The cost is more because higher kWh battery and inverter costs for the 5-kW/20-kWh battery pack plus indirect cost multipliers (profit, sales tax, and supply-chain costs) (Fu et al. 2016). Hardware costs constitute ...
23 Σεπ 2020 · This study presents the initialisation of a hybrid alternating current/direct current (AC/DC) power system to determine the operation point around which the system is linearised as a starting point for an electromagnetic or harmonic stability analysis.
2 Απρ 2021 · This paper presents a two-step state estimation formulation for the monitoring of hybrid AC-DC grids. In the first step, state estimation is executed independently for the AC and DC areas of the distribution system.
