Risk-based uncertainty of power system using bootstrap technique / Siti Rohani Kasim

The main role of a modern electric power system is to provide cost-effective electrical energy to its customers with a high degree of reliability. Hence, power system utility must ensure that they could provide adequate and quality energy supply to customers. However, this has been a major challengi...
