POTENTIAL OF A DECENTRALIZED LOAD MANAGEMENT CONCEPT AND TRANSFERABILITY TO VARIOUS COUNTRIES

Paris agreement signed up from nearly 200 countries in 2015 achieving climate protection goals has led to further package of measures. Governments all over the world decided focusing expansion of renewable energies. This expansion target influences operation and planning of energy grids. One new challenge for stable operation of energy grids is the interplay of difficult-to-predict feed-in of decentralized energy resources and load consumption. Especially photovoltaic systems feed into the low voltage grid, where measurement data are rarely available. Furthermore, the amount of partly flexible loads in low voltage grid is increasing, which might offer possibilities for flexibilization, if used by the Distribution Grid Operators (DSO). The main task of DSO world-wide is to maintain and to re-establish security of supply. In the past, security of supply was rarely discussed for lower voltage levels. However, due to this current evolution it becomes highly relevant. The following shows, that based on currently available measurement data from the grid, a grid wide assessment is hardly possible. The paper further analyses the potential of a decentralized load management concept for optimization security of supply and evaluate transferability of concept to selected countries.
