1. Load DesignCase1_2015 into PowerWorld Simulator. Perform an initial power-flow solution to verify the base case system operation without the TULIP load. Note that the entire line flows and bus voltage magnitudes are within their limits. Assume all line MVA flows must be at or below 100% of the limit A values, and all voltages must be between 0.95 and 1.10 per unit.2. Repeat the above analysis considering the impact of any single transmission line or transformer outage. This is known as contingency analysis. To simplify this analysis, PowerWorld Simulator has the ability to automatically perform a contingency analysis study. Select Tools, Contingency Analysis to show the Contingency Analysis display. Note that the 57 single line/transformer contingencies are already defined. Select Start Run to automatically see the impact of removing any single element. This system has line violations for several different contingencies.3. Using the rights-of-way and the transmission line parameters/costs given in the cost section (Sample Transmission System Design Costs), iteratively determine the least expensive system additions so that the base case and all the contingences result in reliable operation points (i.e., one with no violations) with the new TULIP load. The parameters of the new transmission line(s) need to be derived using the tower configurations and conductor types. Tower configurations are provided by the instructor with default values given with the cost data. Several different conductor types are available in the cost section. The total cost of an addition is defined as the construction costs minus the savings associated with any decrease in system losses over the next 5 years. 4. Write a detailed report discussing the initial system problems, your approach to optimally solving the system problems, and the justification for your final recommendation.
