An introduction to Smart Grid
The world is trying to move away from fossil energy resources and move toward renewable electric energy from natural resources such as sunlight, wind, tides, waves, biomass, etc. Use of electricity for heating, cars, etc. will put additional load on the current electric grid. It requires some measures:
- By having a more tight control of the grid, it is possible to increase its utilisation.
- By taking steps to distribute the energy consumption more evenly across time, it s possible to get a better utilisation of the available energy and the transmission grid.
- By taking steps to reduce the consequences of varied electricity energy production.
All the above requires the establishment of a controlling ICT network parallel with the electric grid resulting in what is called Smart Grid.
One source of energy
The supporting ICT network interconnects a vast number of units resulting in a corresponding vast number of communication connections, where partners have to authenticate each other and where the communication has to be protected by encryption.
The ICT network has to be building on international standards. It is not the intention to discuss such standards here, just to discuss the security aspects, where Public-Key Infrastructure (PKI) plays a major role.
