Poland’s eco fund has granted Stoen Operator, part of German utility E.ON, PLN 12 million (USD 3 million/EUR 2.8 million) to co-finance an energy storage initiative aimed at stabilising Warsaw’s electricity network. The financing comes under the National Fund for Environmental Protection and Water Management’
Warsaw is going to benefit from the construction of ten electricity storage facilities, thanks to a funding boost of over PLN 12 million from the National Fund for Environmental Protection and Water Management (NFOŚiGW).
Battery, Fuel Cell, and Super Capacitor are energy storage solutions implemented in electric vehicles, which possess different advantages and disadvantages.
In EVs, the type of energy storage is, together with the drive itself, one of the crucial components of the system.
Another alternative energy storage for vehicles are hydrogen FCs, although, hydrogen has a lower energy density compared to batteries.
This article proposes an integrated approach that combines stationary and vehicle-mounted mobile energy storage to optimize power system safety and stability under the conditions of limiting the total investment in both types of energy storages.
The switched-capacitor-based inverter design that is being suggested produces five-level output voltages with only two capacitors, one DC source, and seven switching devices. A low-frequency half-height approach is utilized to generate the firing pulses of switching devices in a standalone system for higher output voltage quality and lower THDs.
The flying capacitor inverter combines low semiconductor costs and gives a multi-level output with high output frequency and low dynamic losses. Although the input is only two level with no need for the enormous DC-link capacitor bank, the output is multi-level and the output frequency is a multiple of the switching frequency.
As the converter and inverter blocks have separate controls, this capacitor serves as the voltage reference for the inverter. Implementing photovoltaic (PV) systems as direct power sources for motors without batteries is a complex process that requires a sophisticated control mechanism.
The simulations based on 3kW grid connected PV system are carried out in DIgSILENT Power Factory software. Findings: A capacitor of 410µF is needed to be connected in parallel with a 3kVA inverter having an nominal input voltage of 370V and maintaining a voltage ripple under 8.5%.
