  • What is the advantage of reactive power?Practical example: electrical grid with an overhead transmission network Grid connection point Residential connection 2 Medium voltage grid Residential connection 1 Connecting line Transformer P P P 20 kV 0,4 kV Load 2 Load 1 UL1 1,1 p.u. = 253 V 1,0 p.u. = 230 V Length (distance) 0,9 p.u. = 207 V Max. Load (with voltage adjustment) Max. Load (without voltage adjustment)  Until now the distribution grid was dimensioned for the consumption case 06/2011 How to connect in case of high electrical impedance of the grid? 30
  • What is the advantage of reactive power?Practical example: electrical grid with an overhead transmission network PV Grid connection point Residential connection 2Medium voltage grid Residential connection 1 Connecting line Transformer P 3~ P P ~ P 20 kV 0,4 kV Load 2 Load 1 UL1 1,1 p.u. = 253 V High feed-in with PV PV power at a weak load 1,0 p.u. = 230 V Length (distance) Max. Load (with voltage 0,9 p.u. = 207 V adjustment) The problem with maintaining the voltage level was achieved until now, by expensive grid expansion including a lot of copper in new cables or stronger transformators. 06/2011 How to connect in case of high electrical impedance of the grid? 31
  • What is the use of reactive power? Often overvoltage is a problem in combination with PV plants connected to the local low voltage distribution grid. The new postulation in Germany demands that PV plants are supposed to participate in upholding grid stability during transiently voltage breakdowns (e.g. a close or far short circuit) Typical Portuguese problem: Many small Portuguese low voltage grids have high impedance due to small transformers and small cable cross sections. 06/2011 How to connect in case of high electrical impedance of the grid? 32
  • The problem with phase symmetry AC Power grids are available with three phases (L1; L2; L3) Theoretically the voltage should be the same for all three phases compared to the neutral phase. In practice these three phases are never loaded identically. Consequently there are different voltages on each of the three phases This makes it more difficult to implement a line regulation within the allowed tolerances, because none of the three phases (voltages) is allowed to be outside the tolerance (+/- 10%). Concluding from these issues, the larger the voltage fluctuations, the more important it is to acquire identical voltages within the three phases as far as possible. 06/2011 How to connect in case of high electrical impedance of the grid? 33
