6 FAQs about [Botswana smart grid topology]
Is there scope for a smart mini grid in Botswana?
Development of community-based grid in villages Rural villages in Botswana remains poorly electrified. Given the scope and success of the PV systems, there is huge scope for forming a SMART Mini Grid -based electrification. These Smart Mini Grids could include smart futures after practical considerations.
What are the challenges of smart grid in Botswana?
As Botswana gears up for investment in the Smart Grid technology hugely to meet its growing energy demand in the country, with the transition from analogous to digital electricity, there are numerous infrastructure challenges associated with it. One of the key challenges is in communication.
What is smart grid VPP in Botswana?
Smart Grid VPP model is an emerging technology in Sub-Saharan Africa as compared to other nations across the globe. There are inherent challenges in the smart grids. These challenges need to be taken into account when implementing and deploying smart technologies in Botswana.
How will smart grid—virtual power plant change the business model?
Since Smart Grid—Virtual Power Plant has got the potential to change the business model of electricity generation, it will dictate on where, when and how energy is produced. In this scenario, every household and business will be a prosumer as well as a consumer since they will act as small micro generators.
What are the benefits of village connected VPP in Botswana?
The assurance on the sustainable income will be from selling the excess produced electricity back to the grid through the village connected VPP. This will also enhance and strengthen the bond among the community since their livelihood will depend on the energy from community grid. Fig. 7. Smart mini grid model for rural villagers in Botswana.
What is data access and ownership in the smart grid?
Another critical element related to data access and ownership in the smart grid is data privacy. Since it is closely related to internet resources, it is essential that the privacy of the consumer or prosumer, in this case, is respected. This raises a fundamental question as to how safe the data is to the prying eyes of others.
