A multicriteria model for selecting renewable energy systems in a distributed generation context

One of the challenging tasks that Smart Grids deal with is how to integrate distributed generation (DG) and renewable energy systems (RES). An important aspect in Smart Grids is that both demand and distributed generation (DG) are directly connected to the distribution network. The greater the numbers of DGs in a distribution network are, the more complicated it is to decide what the optimal DG outputs are, especially as two problems to do with voltage regulation and reverse power flow frequently arise. Multicriteria decision making models can be useful to support distribution operators to overcome their problems. A numerical application illustrates the use of a multicriteria decision making model for selecting what RES should be switched off in case of overgeneration.
