The winning answer:
The smart-er grid, as one should probably best put it, is the way towards a constant improvement of the way that power is produced and delivered to the end-customers in a reliable, "green" and cost-efficient way. The concept of the Virtual Power Plant (VPP) is probably the most promising breakthrough towards the above target. However, it has to be realistically implemented.
By organizing generaτion (both central and distributed) and interruptible loads in clusters of separate ownerships and control blocks that operate within a consistent and comprehensive framework, will enhance the actual implementation of the smarter grid. A mix of fossil-fueled stations and renewable energy sources in each VPP will account for the greener prerequisite, while the combination of fast and efficiently controlled topologies in generation (power electronics) and distribution (smart meters) of the VPP realizations will pay for the optimized power quality offered to the customers. On the same time, the participation of the recently developed renewables in the energy markets will be normalized through the incorporation of the former in a wider and also conventional portfolio. That way, the anomalies observed in the first stages of the deployment of renewables (biased feed-in tariffs, investment subsidies, etc) will be eradicated. The role of power engineers towards the smarter future of the grids is already major and reaches out to applied solutions waiting to be identified for extensive use and application. Further research is certainly required, nevertheless the fit-and-forget strategy cannot solve the problems to come - and they will come.
