- What are the problems that may encounter in Development of a sustainable smart grid infrastructureBriefly explain the functions of smart grid.The Electricity Company of Ghana (ECG) has set up a system for reporting power supply faults in the Greater Kumasi Area, including high or low voltage and frequent power outages. Customers can contact ECG customer service and report their issue, providing their ECG pole reference number. The faults are recorded and sent to the ECG Fault Office for action. However, there is a delay in resolving the faults, and clients have to make several follow-up calls to check on the status of their complaints. The ECG management team conducted a survey and found out that customers want their faults resolved within three hours, and any delay beyond that is unacceptable. The team is looking for a solution that will offer a seamless experience to customers and minimize time and effort wasted. a) Given the information above, and making reasonable assumptions, model the current (‘AS IS’) and explain business processes at ECG Fault Office. b)What would the future state (ASTOBE) look like?Provide a new…

- Question 2 A generator having H = 6.0 MJ /MVA is delivering power of 1 .0 per unit to an infinite bus through a purely reactive network when the occurrence of a fault reduces the generator output power to zero. The maximum power that could be delivered is 2.5 per unit. When the fault is cleared, the original network conditions again exist. Calculate: a) The critical clearing angle. b) The critical clearing time.Power System Analysis (522EE) 431 It is recommended to use a software program to solve the nonlinear equation in Q2 (b). Question 1: Figure 1 shows a single-line diagram of a three-phase, 60-Hz synchronous generator, connected through a transformer and parallel transmission lines to an infinite bus. All reactances are given in per-unit on a common system base. If the infinite bus receives 1.0 per unit real power at 0.95 p.f. lagging, determine (a) the internal voltage of the generator and (b) the equation for the electrical power delivered by the generator versus its power angle 8.
