AppendixINTRODUCTION As a result of the low electric rates from the local utility, Metropolis Light and Power (MLP), several large server farms and a new factory are going to be built in the eastern portion of the MLP service territory. With an anticipated peak load of about 75 MW and 20 Mvar, this new load also brings additional revenue to MLP. However, in order to supply this additional load, the new TULIP substation will need to be constructed. While they would like to receive electricity at the69 kV level, the new substation location is large enough to accommodate a 138∙69 kV transformer if needed. Additionally, for reliability purposes, the TULIP substation needs to have at least two separate lines into their substation. PURPOSE AND GOAL OF THE PROJECT As a planning engineer for MLP, your job is to make recommendations to ensure that, with new TULIP loads under peak loading conditions, the transmission system in the eastern region is adequate for any base case or first contingency loading situation. This is also a good opportunity not only to meet the new load, but also to fix some existing first contingency violations in the eastern portion of the MLP service territory. Table-1 shows the available right-of-way distances that can be used for the construction of new 69 kV and/or new 138 kV lines. All existing 69 kVonly substations are large enough to accommodate 138 kV as well. It is my job to iteratively determine the least expensive system additions so that the base case and all the contingencies result in secure operation points. The parameters of the new transmission line(s) will be derived using the tower configuration and conductor types available. 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 five years. I will be using the PowerWorld Simulator to conduct my studies. Any data assumed or referenced will be listed in the Appendix for reference. I will use the PowerWorld DesignCase1_2015 for the purpose of the study. Simplifying Assumptions:
