    COMPARISION OF DIFFERENT TECHNIQUES FOR MITIGATION OF UNDER VOLTAGE PROBLEM OF BANGLADESH POWER SYSTEM AND THEIR EFFECT ON STABILITY
    (DEPARTMENT OF ELECTRICAL, ELECTRONIC AND COMMUNICATION ENGINEERING, 2017-12) Sarker Utsha, Manobendro; Nabil, Shadman Shakib; Rahman, Md. Mahmudur
    Power quality has become a major concern because of increasing number of loads being connected to the power system. Abnormal conditions in a power system create fluctuations to electrical quantities such as voltage, frequency and current. An important factor in the normal and healthy operation of the power system is to maintain security in power generation, transmission and distribution. System security can be assessed by solving under-voltage problem. In this thesis power flow analysis of Bangladesh Power System is performed by PSAF (Power System Analysis Framework) and three different solution method of under-voltage problem is shown along with cost calculation for each of the methods. Afterward, transient stability analysis is done for each of the methods considering four different abnormal events taking one at a time. A comparative conclusion is shown on the basis of cost effectiveness and stability for the adopted solution methods.
