Let us consider the a small village. The power network of the village is shown in Figure 1. Load demands at Zone A, Zone B and Zone C, are 5MVA (0.95pf lagging), 7MVA (0.94pf lagging) and 7MVA (0.94pf lagging) respectively. Per kilometre line resistance and reactance connecting the zones are 0.0001pu and 0.005pu respectively. The base MVA and voltage are 100MVA and 11kV. 15 Km Ⓒ-8-3-0 Zone B Figure 1: The structure of the village under consideration. ● Diesel 30 Km/ Generator, Zone A Km Zone C The aim of the company you are working is to install PV and wind generators in zones B and C respectively. Design Specifications: 20% of the total real power load demand is required to be supplied by the renewable energy resources. The voltage magnitudes at each of zones are required to be maintained with in +2% of the rated or base voltage. The voltage angles of the zones are required to be maintained such that at least stability margin of 80 degrees is maintained throughout the network. Part A: You describe the existing power network in the village by completing the following steps. 1. Draw the single line diagram of the existing power network of the village. 2. Formulate a load-flow problem such that the power flow and voltage profile of the village power network can be determined by SIMPOWER system toolbox. 3. Develop the existing power network model of the village in SIMPOWER system tool box. 4. Determine the power loss in the network. 5. Demonstrate the real and reactive power balance of the existing network. Part B: You describe the power network in the village after inclusion of the DG units by completing the following steps. 1. Draw the single line diagram of the power network of the village with the distributed energy systems included in Zones B and C. 2. Formulate a load-flow problem such that the power flow and voltage profile of the village power network can be determined by SIMPOWER system toolbox. 3. Develop the power network model of the village in SIMPOWER system tool box including the distributed energy resources in zones B and C. 4. Determine the power loss and the power balance in the network. Compare the results in part A and B and highlight the benefits of installing DG units in terms of system loss, voltage profile and stability margin. Let us consider the a small village.
