Rubric get_task_times() implementation (6 points) 6pts: Accurately prompts for 5 times, calculates the average after removing the highest (slowest) time, and prints the output. 3pts: Some functionality is correct (e.g., prompts for times, calculates an average) but fails to correctly drop the highest time or format the output. 0pts: Missing or completely non-functional implementation. get_contestant_name() implementation (2 points) 2pts: Correctly prompts the user for the contestant’s name and returns it as a string. 1pt: Returns a name but has minor issues (e.g., formatting or incorrect data type). 0pts: Missing or completely non-functional implementation. get_task_scores() implementation (5 points) 5pts: Prompts for integers between 1 and 5, validates input, stores valid integers in a list, and stops when “Finish” is entered. Handles invalid input with clear error messages. 3pts: Partial functionality (e.g., accepts integers but lacks proper input validation or fails to stop correctly when “Finish” is entered). 0pts: Missing or completely non-functional implementation. print_score_board() implementation (5 points) 5pts: Prints the contestant’s name and a clean histogram where each list element corresponds to a row of hash symbols. Output matches the example format. 3pts: Prints the graph with minor formatting or logic issues (e.g., incorrect number of hash symbols or unorganized layout). 0pts: Missing or completely non-functional implementation. Program compiles and runs when copied and pasted directly from student submission. (2 points)

Question 1 Economic dispatch: A power system includes two generators serving load demand \(d=1\) per unit (pu). Their generation costs and limits (in pu and \$/pu) are shown below:\begin{align*}c_1(p_1)&=300p_1^2+200p_1, &&\underline{p}_1=0,~\bar{p}_1=0.9.\\c_2(p_2)&=200p_2^2+300p_2, &&\underline{p}_2=0,~\bar{p}_2=0.8.\end{align*} (a) Formulate the economic dispatch and find the optimal generation dispatch. (b) What is the price of electricity for this system? Calculate the net gain for each generator. (c) How much money does the independent system operator (ISO) collect from the load, and how much money does the ISO distribute to GENs? (d) Compute the participation factors for the two generators.   Question 2 Power flow: Consider the 3-bus power system shown below. Line impedances are given as \(x_{12}=0.2\) and \(x_{23}=x_{31}=0.1\) pu. Bus 1 is set as the reference and slack bus and we adopt the linearized (DC) PF model. (a) Find matrices \(\mathbf{X}\), \(\mathbf{A}\), \(\mathbf{B}\) and the reduced matrix \(\mathbf{B}_r\), involved in the DC-PF model.  (b) The vectors of power flows \(\mathbf{f}\) and power injections \(\mathbf{p}\) are related as\[\left[\begin{array}{c}f_{12}\\f_{23}\\f_{31}\end{array}\right]=\mathbf{S}\left[\begin{array}{c}p_{1}\\p_{2}\\p_{3}\end{array}\right]\quad \quad \text{where}\quad \quad\mathbf{S}=\left[\begin{array}{ccc}0 & -0.5 & -0.25\\0 & +0.5 & -0.25\\0 & +0.5 & +0.75\end{array}\right].\] Find the bus voltage angles for injections \(\mathbf{p}=[+0.7~+0.3~-1]^\top\). Question 3 Network-constrained optimal power flow: Using the generation/load data of Q1) and the network data of Q2), the ISO solves a DC-OPF. Line capacities are given as \(\bar{f}_{12}=0.4\),  \(\bar{f}_{23}=0.4\), and \(\bar{f}_{31}=0.8\) pu. The optimal dispatch is \(\mathbf{p}=[+0.7~+0.3~-1.0]^\top\). The marginal energy component is $620. Among the three lines, line \((2,3)\) gets congested and reaches its upper limit. The corresponding Lagrange multiplier is $400. (a) Find the vector \(\boldsymbol{\pi}\) of locational marginal prices at all buses. (b) How much money does the ISO pay each generator? How much money does the ISO collect from the load? Calculate the congestion surplus. Question 4 Contingency analysis: For the system of Q3) and power injections \(\mathbf{p}=[+0.7~+0.3~-1.0]^\top\), find the post-contingency flow on line \((2,3)\) if line \((3,1)\) trips.  Is the system in this post-contingency state secure? Question 5 For each of the following statements related to the (lossless) DC-OPF model, mark if they are true or false: (a) Building more transmission lines can only decrease the total generation cost.  (b) Building more generators can only decrease the total generation cost. (c) LMPs are equal across all buses only if there is no congestion. (d) The power injections obtained from the DC-OPF are also feasible for the AC-OPF. (e) The corrective security-constrained SC-DC-OPF yields a lower total generation cost compared to the preventive SC-DC-OPF. (f) The corrective SC-DC-OPF may yield lower total generation cost compared to the plain DC-OPF. Question 6 Unit commitment: The generators of Q1) are given the price of $500/pu to generate power for the next hour. (a) If GEN1 is currently off and its start-up cost is $50, what would be the self-dispatch for GEN1? (b) If GEN2 is currently off and its start-up cost is $100, what would be the self-dispatch for GEN2?

Claire is a 45-year-old client with a diagnosis of Generalized Anxiety Disorder with primary insomnia and has been transferred to your care from one of your colleagues who is out on leave. Claire has been prescribed the same medication regimen for the past 10 years: alprazolam 0.5mg, take 2-3 tabs daily, as needed (automatic refill every 3 months) zolpidem 10mg HS, as needed for sleep (automatic refill every 3 months) Claire usually takes: 2-3 tabs of alprazolam, 5-7 days per week & zolpidem 10mg QHS At her appointment, Claire describes significant job-related stress and pressure that increase her anxiety and insomnia, and that she cannot sleep without taking zolpidem. Claire explains that with previous attempts to decrease the dose of alprazolam her anxiety got much worse, and she is adamant to not make any changes to the current treatment plan. She views the medication as beneficial and values that her trusted provider had her best interest in mind. You explain that she is likely experiencing dependence to the alprazolam, experienced rebound anxiety related to withdrawal, and that you would like to address her medication regimen. Claire is still resistant to changing medication. You elect to not challenge the zolpidem at this time but continue to have concerns about the alprazolam. Use this scenario for the next 4 questions. Answer each Issue in a separate blank below and number your answers: 1: Do you respect the patient’s wishes or change the medication re: clinical indications, efficacy, and safety concerns? (1 points) 2: How do you maintain professionalism around your peer provider re: medication plan? Is it worth confronting your peer? (2.5 points) 3: How do you make a decision between what is ‘best’ for the patient given the surrounding negative consequences? (1 points) 4: How do you proceed? (2.5 points)
