1,000 new vacation homes
Europarcs has extended their vacation park at Kaatsheuvel close to Efteling with 1,000 additional vacation homes. This is a result of more people going on vacation in their own country due to corona. To support this extension a new transformer substation was ordered, but due to delivery times being long, the grid expansion could not be delivered on time. The grid connection at the time had a maximum current of 580 ampere and overloading could lead to power failure. Europarcs was searching for a clean solution, which leverages the available power.
Smart grid with Greener EMS
Together with Europarcs, Greener first looked at historical data of energy use, data on new energy users, the weather and combined that with the data Greener had from past projects. As a result of this analyses, Greener recommended a smart grid with the Greener Energy Management System (EMS) and three batteries. The EMS measures the available transformer’s power, controls the three batteries and in case of a capacity shortage can start-up a back-up generator. Therefore, the transformer is metered to keep the maximum current below 580 amperes. Additionally, one of the three batteries was used to boost the voltage of the grid connection, since drawing large volumes of power can lead to a lower voltage and grid instability. During the project, the EMS was responsible for ensuring that the batteries charge and discharge energy optimally and the generator was used as little as possible.
Because the EMS monitored all data from the grid connection, diesel generator and batteries, it was possible to use the power supply as efficiently as possible.
