Abstract

The effects of load frequency control (LFC) of interconnected distribution power system in tie-line substation area, load – frequency stability and the frequency respond at distribution generator (DG) are very important for interconnected control power system of tie – line area. The generating power system of solar farm and wind turbine which have interconnected distribution power system in tie – line substation area were tested using 3 simulation parameters: non-controller, Automatic Voltage Regulator (AVR) and with PI Controller. The results showed that there were 3 types of load and frequency changing in the interconnected area: load changed 0.02 p.u. had frequency of load changed 0.025 Hz and large disturbance. Comparisons of load - frequency to respond for steady state, the time respond was 7.9 seconds for non-controller, 5.4 seconds for AVR and 1.7seconds for under controlled system at 0.1 p.u. using PI controller. Therefore, the PI controller has better efficiency than non-controller about 31 % and AVR about 16 %. It can be concluded that the interconnected distribution power system in tie-line substation area controlling for storage for connected grid had better efficiency and optimization of generating power from renewable solar farm and wind turbine which have interconnected distribution power system in the nearby are balance of controlling of the original system.
