| Abstract | Automatic generation control (AGC) has been one of the important issues in the operation of local area and interconnected power systems. AGC provides power demand signals for AGC power generators to control frequency. In AGC, some variables of power system such as frequency and power generation are measured to calculate the area control error (ACE). The ACE value is an important factor of AGC performance. Generally, ACE value is determined by a constant frequency bias factor of power system or 1% of load method. The ACE value based on the constant frequency bias factor or 1% of load method, however, may not represent the real time status of power system correctly. The incorrect ACE value is a cause of over regulation of power system. This paper presents the method to decide actual frequency bias factor on real time frequency characteristics. In this paper, the actual frequency bias factor is determined by the measured variables such as generator power output change and frequency deviation due to disturbance of power system. The actual frequency bias factor calculated is used to determine the ACE of power system. The AGC divides the calculated ACE among AGC power generators periodically. The period is determined by the time of recovered frequency. This paper also presents the simulation results for the power system model about the proposed AGC scheme. The simulation results show that the performance of AGC is improved when the proposed AGC scheme is applied to AGC. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
