Abstract (eng): | Due to high electricity load growth there is requirement of enhancement of power system network capacity. However, additional capacity requires huge investment. These investments correspondingly increase cost of electricity on customers. To sustain in competitive electricity market, high network efficiency is also necessary. Therefore, there is need to find a way to utilize already kept reserve capacity in the network. Can Demand Response and Electrical Vehicles, Smart Grid features, be utilized to mitigate the reserve capacity requirement? To find the potential of DR in mitigating the reserve requirements, analysis is conducted in the thesis. Network outage cost is calculated considering different load growths without investing into network. Then decrease in outage cost due to DR in same network is computed. The difference expresses the required potential of DR. The results of various case studies show that EVs are not able to decrease reserve requirement of grid mainly because their availability at required time is very low. DR potential is also not convincing. Even for low load growth, huge DR resources are required to mitigate the reserve capacity requirement. Study results can be exercised to delay investment in capacity for low growth after comparing with investment cost required. Further evaluation of potential of DR along with Distributed Energy Resources (DER) is needed. |
