Consider that there is a load pocket in your system with a 2000 MW load and an unacceptable level of energy not served due to loading transmission limitations under contingency. What options would you consider for improving this situation (select all that apply)
a. Implement underfrequency / undervoltage load shedding protection. b. Add local resources including storage and generation
c. Add new transmission lines
d. Evaluate the reasons for frequent line trips and why there is long duration for recovery.
e. Add more generation to the external system.
15. After conducting our evaluation in the caseTabove we found that the local resources was able to reduce the energy not served by 50% and the new lines eliminated them completely. What would you do next (select all that apply)?
a. Select the transmission solution.
b. Select the local resource and live with the 50% remaining energy not served.
c. Assess the cost of the local generation solution + the cost of the energy not served
and compare it with the cost of transmission.
d. Evaluate if demand response would close the gap to the transmission solution.
16. Consider the situation in the figure below where A1 > A2. What can you say about this?
