AEG Power Solutions, a global provider of power electronic systems and solutions for industrial power supplies and renewable energy applications, today announced it has developed a unique Hybrid Energy Storage System which combines standard battery storage with power-to-heat technology to reduce the total cost of energy storage operation.
The solution can be installed in any type of facility which uses thermal processes, including local heat networks in combination with an electrical distribution network.
With the Hybrid Energy Storage solution from AEG PS, the power conversion system (PCS) becomes the central key element operating the power management and controls both the battery as well as the heating system. The PCS and all equipment required for grid connection (e.g. transformer and switch gear) therefore are used for both the batteries and the heater. The platform allows for all typical applications of standard battery energy storage in particular, frequency regulation; bby combining both systems, the capacity of the thermal storage adds up to the battery storage capacity.
“Technically, in a stand-alone battery energy storage system, explains Andreas Becker, Product Manager at AEG Power Solutions, it’s necessary to keep a battery charge stable at the 50% level in order to provide grid frequency regulation. By combining it with a power to heat system, we allow extra energy to go to the thermal process. The battery can then operate at 100% capacity.”
This in fact leads to dividing the battery total capacity required by almost two. Taking into account that they represent usually around 70% of an energy storage installation, the economic benefit of the innovation is obvious and the payback period of the investment is approximately 3 years faster in a primary control power market.
AEG Power Solutions engineers the complete solution and provides the key components such as the power conversion hardware and the power management software.
AEG PS is an innovator in energy storage and management thanks to its many decades of experience in the world of UPS, power electronics, batteries as well as international grid connection compliance. This unique combination of know-how has been leveraged to design products and solutions for energy storage.
Factories Act 1961 – Memorandum on the Electricity Regulations
Today I was having a look at some old books I had and I found a copy of the Factories Act 1961 – Memorandum on the Electricity Regulations produced by the Health and Safety Executive. Makes an interesting read, some old ways of working in this one !
18th Edition Regulations – Energy Efficiency
The worldwide need to reduce the consumption of energy means that we have to consider how electrical installations can provide the required level of service and safety for the lowest electrical consumption. The draft proposals enable a client to specify the level of energy efficiency measures applied to an electrical installation. Installations can also be awarded points for energy efficiency performance levels, for example, transformer efficiency. These points can be added together with points for efficiency measures to give an electrical installation an efficiency class, ranging from EIEC0 to EIEC4, depending on the number of points awarded.
The new section will cover several energy efficient areas, such as electric vehicles, lighting, metering, cable losses, transformer losses, power-factor correction, and harmonics.
18th Edition Wiring Regulations
According to the IET The 18th Edition of the Wiring Regulations is due to be published on 1st July 2018.

The Amazing Folding UK Plug
We found this amazing plug when looking on line this week. The history behind it is from The Royal College of Art’s graduate show, and the show-stopper was this plug. Min-Kyu Choi impressed every passer by with his neat, apparently market-ready plug that folds down to the width of an Apple MacBook Air. “The MacBook Air is the world’s thinnest laptop ever. However, here in the UK, we still use the world’s biggest three-pin plug,” says Choi.
As with many things it started with a problem; the size of the UK plug versus the products that they serve. Min-Kyu Choi had a direct encounter with this having discovered a scratch on his laptop being caused by the UK plug in his bag. The UK plug, having been designed in 1947 when portability was not a consideration, had long since become outdated.
Min-Kyu set about solving the problem. Min-Kyu Choi and Matthew Judkins came together in 2009 to make Min-Kyu’s solution a reality. Having subsequently won a number of awards and having seen a concept video receive over 500,000 hits, their first product was launched in 2012 under the crowd sourced name ‘Mu’.
