This document discusses optimization in power systems. Optimization aims to find the maximum and minimum values of functions, and can be used to optimize various systems including power networks, transportation, and more. In power systems specifically, optimization becomes important as systems grow larger and more complex over time due to increasing demand. Optimization techniques can save power utilities hundreds of millions annually through reduced fuel costs and improved reliability while meeting environmental standards. The key goals of optimization in power systems are minimizing generation costs and maximizing social welfare while satisfying operational constraints.
Optimization in power system
- 1. OPTIMIZATION IN POWER SYSTEM It is hard for power to enjoy or incorporate humor and satire in its system of control Dario Fo HASSAN KHALID UPPAL 15-EL-40 Sir SAADULLAH CHANDIO
- 2. What Is Optimization? • Optimization is the mathematical discipline which is concern with finding the MAXIMA and MINIMA of function, possibly subject to the constraints for continuous and differential functions. • It is derived from the Latin word “Optimus”. 3/20/2018QUEST | NAWABSHAH | PAKISTAN 15-EL-40 2
- 3. Where Can We Use Optimization? Architecture Electrical Network Economics Material Design Image Processing Transportation Nutrition … etc. 3/20/2018QUEST | NAWABSHAH | PAKISTAN 15-EL-40 3
- 4. What Do We Optimize? A real function of N variable f(X1,X2,X3…Xn) With or Without constraints 3/20/2018QUEST | NAWABSHAH | PAKISTAN 15-EL-40 4
- 5. Methodology Of Optimization Techniques Identify the problem or opportunity Understand the system Formulate a Mathematical Model Verify the Model Select the Best Alternative Present the result of the Analysis Implement and Evaluate 3/20/2018QUEST | NAWABSHAH | PAKISTAN 15-EL-40 5
- 6. Identify the problem or opportunity Understand the system Formulate a Mathematical Model Verify the Model Select the Best Alternative Present the result of the Analysis Implement and Evaluate What are the objectives? Is the proposed problem too narrow? Is it too broad?
- 7. Identify the problem or opportunity Understand the system Formulate a Mathematical Model Verify the Model Select the Best Alternative Present the result of the Analysis Implement and Evaluate What data should be collected? How will data be collected? How to different components of the system interacted with each other?
- 8. Identify the problem or opportunity Understand the system Formulate a Mathematical Model Verify the Model Select the Best Alternative Present the result of the Analysis Implement and Evaluate What kind of model should be used? Is the model accurate? Is the model too complex?
- 9. Identify the problem or opportunity Understand the system Formulate a Mathematical Model Verify the Model Select the Best Alternative Present the result of the Analysis Implement and Evaluate Do output match current observation for current inputs? Are outputs reasonable? Could the model be erroneous?
- 10. Identify the problem or opportunity Understand the system Formulate a Mathematical Model Verify the Model Select the Best Alternative Present the result of the Analysis Implement and Evaluate What if there are conflicting objectives? Inherently the most difficult step. This is where software tools will help us!
- 11. Identify the problem or opportunity Understand the system Formulate a Mathematical Model Verify the Model Select the Best Alternative Present the result of the Analysis Implement and Evaluate Must communicate results in layman’s term. System must be user friendly!
- 12. Identify the problem or opportunity Understand the system Formulate a Mathematical Model Verify the Model Select the Best Alternative Present the result of the Analysis Implement and Evaluate User must be trained on the new system. System must be observed over time to ensure it works properly!
- 13. Optimization In Power System Power system engineering has the longest history of development among the various areas of electrical engineering. Power system are getting larger and more complicated day by day because of: >>Increase of load demand >>Fossil fuel demand of thermal power plants 3/20/2018QUEST | NAWABSHAH | PAKISTAN 15-EL-40 13
- 14. When the Power Systems are getting larger and more complicated day by day then their will be some limitations like: >>Rising costs >>Rising emission into the environment Therefore, optimization is become essential for the operation of power system utilities in term of: >>Fuel cost saving >>Environmental preservation Importance of Optimization In Power System 3/20/2018QUEST | NAWABSHAH | PAKISTAN 15-EL-40 14
- 15. Numerical optimization method have played a very important role in Power System Optimization. Through Power System Optimization economical term with Hundreds of Millions of Dollars saved annually in large utilities. >>Fuel cost >>Improved operational reliability >>System security Importance of Optimization In Power System 3/20/2018QUEST | NAWABSHAH | PAKISTAN 15-EL-40 15
- 16. Optimization Aim & Focus To minimize the cost of power generation in regulated power system. To maximize social welfare in deregulated power system, while satisfying various operating constraints. 3/20/2018QUEST | NAWABSHAH | PAKISTAN 15-EL-40 16
