INTRODUCTION

In this study, we investigate how a Big Data approach of large connected data sets can contribute to addressing supply-demand balancing. The objective of the study was to answer the following research questions

1. How is the local generation associated with local demand over time?

2. What are the possible strategies to address the cumulative supply-demand mismatch?

3. What are the appropriate strategies for time resolved balancing?

METHODOLOGY DESCRIPTION

1. Collect data

2. Create clean and useable datasets

3. Add spatial entity for visualization and analysis in GIS.

4. Make meaningful conclusions

The pilot area we chose is defined by the Dutch postal codes 73 and 81. This area covers the city of Apeldoorn and rural villages like Vaassen, Epe and Heerde. The time resolution we used is one hour, and the spatial resolution varying between household level to postal code. The analysis started with the mapping of installed systems, capacity and production, building information, digital elevation models, solar potential and electricity consumption.

Scenario : If the household had a solar panel

Electricity consumption of a household (4216 kWh) Electricity production from a 2.25 kWp installation in the same area (1767.6 kWh )

Interim Conclusions

We were able to bring for the pilot area data sets from different sources onto the same GIS base.It was found that about 1.61% of the total electricity consumption is covered by PV in the pilot area for the domestic sector. Therefore, there is scope for filling this gap. Grid operators would have to keep track of all the ongoing installations and be able to manage the feed–in and the consumption and consumers will be able to understand and forecast the generation of solar power as a function of place and time which will enable smooth management of supply and demand. We performed a new analysis of PV potential based on the AHN elevation data. The roof potential is not large enough for 100% coverage of the electricity demand. About 39% coverage can be achieved by rooftop PV. Time resolved balancing will require a combination of demand steering (variable tariff setting) and storage.

A method to find the PV potential from elevation data. This method has been used to find the potential capacity and would be implemented for future calculations.
