renewable energy in zaanstad: from theory to practice - e-harbours

ecause of environmental and social reasons. By learning from this Smart Grid pilot project Zaanstad
can gain knowledge to develop the electric infrastructure necessary to support the plans for
renewable energy by 2020. This way Zaanstad can develop a business case for the possible roll-out of
a Smart Grid over the municipal organization. The components on the production side consist of:
I. 10 kWp of PV cells at location ‘Fietsenpakhuis’
II. 10.2 kWp of PV cells at location ‘Van Serooskerkelaan’
III. 10.2 kWp of PV cells at location ‘Havengebouw’
IV. A wind turbine simulation model 5
The consumers are the 16 electric vehicles of the municipal organization. Figure 15 shows a
schematic overview of the REloadIT project.
Figure 15. Schematic overview of the REloadIT concept
The objective is to charge the electric vehicles by solar and wind energy and do this in a smart way by
using information and communication hard- and software. To achieve, the production and the
consumption need to be forecasted in a detailed and accurate way. To forecast this consumption, an
accurate planning of the electric vehicles usage by the municipal employees needs to be available.
On the production side, a meteo forecaster will be installed to forecast the PV production as detailed
as possible. The Smart Grid software will use both forecasting data to calculate ahead if supply and
demand can be matched. If there will be an underproduction, the Smart Grid data center will use a
virtual electricity market to suggest optimal financial decisions. This means, selling surplus electricity
when the electricity prices are high, and buying shortage on electricity when the prices are low. The
5 There are no wind turbines installed in the context of the REloadIT project yet, so this will be simulate.
