Advancing microprocessor technologies have brought automation capabilities to new levels of applications. Load frequency control of power systems (also called automatic generation control – AGC), is one of many important industrial application areas, which may greatly benefit from such advances. However, development and deployment of such applications are often difficult because of the complex ...

In this paper the model of hybrid power system is developed. It comprises two thermal power generation system with Photovoltaic generation system (PV), wind turbine, fuel cell, aqua electrolyzer and battery storage system. To maintain the preferred frequency and power exchange with the neighboring system in the hybrid power system is the objective of Automatic Generation Control (AGC). The devi...

in this article, an effective method to control a power system during emergency conditions is presented. based on fuzzy linear programming (flp), a new technique is developed to solve the load shedding and generation reallocation (lsgr) optimization problem. the objective function consists of terms of load curtailments and deviations in generation schedules. the constraints are power system var...

Switching frequency acts as a major role, while applying sliding mode control to dc-dc buck converter, switching frequency is affected by line and load variations. To reduce switching frequency deviation to line and load variations, an adaptive feed forward control is used, that varies hysteresis band according to the change of input voltage. Several methods of varying hysteresis band of the hy...

With the increasing penetration of renewable energy resources, power systems face a new challenge in balancing power supply and demand and maintaining the nominal frequency. This paper studies load control to handle this challenge. In particular, a fully distributed automatic load control algorithm, which only needs local measurement and local communication, is proposed. We prove that the contr...

In a deregulated environment, independent generators and utility generators may or may not participate in the load-frequency control of the system. For the purpose of evaluating the performance of such a system, a flexible method has been developed and implemented. The method assumes that load frequency control is performed by an ISO based on parameters defined by the participating generating u...

Bevrani, Hassan (2004) Decentralized robust load-frequency control synthesis in restructured power systems. Preface This dissertation is mainly focused on technical issues associated with load-frequency control (LFC) in restructured power systems. Operating the power system in a deregulated environment is more complex than in the past, due to the considerable degree of interconnection and the p...
