People often ask us about energy self-sufficiency. Just how hard is it to get to that point where you no longer have to pay a large corporation each time you turn on the kettle? This will depend on your usage patterns but for most people, a mix of renewable systems is the best option. We’ve taken a look at Gabriel’s home renewable systems as an example. Perhaps unsurprisingly, ...

At least since the end of April, when Tesla introduced its Powerwall, everyone seems to be talking about the market for stationary battery-storage systems. At any rate, it was the dominant topic at Intersolar. I asked Volker Wachenfeld, an SMA expert in storage technology, about his assessment of the market and SMA’s plans for battery-storage systems going forward. - See more at: ...

The Indian government had an initial target of 20 GW capacity for 2022, which was achieved four years ahead of schedule. In 2015 the target was raised to 100 GW of solar capacity (including 40 GW from rooftop solar) by 2022. The ambitious target has brought along with it the need to review the existing energy policies in order to satisfy all the stakeholders like prosumers, DISCOMs, energy ...

The battery charging system is a critical part of a plug–in hybrid electric vehicle (PHEV). The efficiency, charging speed, and cost of such chargers are crucial to the commercialisation of PHEVs. In this paper, the advantages and drawbacks of four potential PHEV charger topologies were compared based on their operations through simulation and experiments. Their electrical stress, efficiency, ...

Distributed electricity generation, especially solar PV, is rapidly spreading and getting much cheaper. Distributed electricity storage is doing the same, thanks largely to mass production of batteries for electric vehicles. Solar power is already starting to erode some utilities' sales and revenues. But what happens when solar and batteries join forces? Together they can make the electric grid ...

In this paper, a STATCOM interfaced battery energy storage system (BESS) is considered for smoothing intermittent power output of a large wind farm so that it can be dispatched. The main advantage of the system is that it can inject both real power (by charging/discharging the BESS) and the reactive power to the system. The paper investigates the main design issues related to BESS – the control ...
