This paper proposes HNF approach for the applications of AGC of a hydro-thermal and Thermal-thermal systems in a power system deregulated environment. It makes an attempt to provide a new practical AGC model with Generation Rate Constraints to fulfill the needs of modern restructured interconnected systems in a Deregulated Environment.

This paper presents a forward recursive procedure to calculate the expected system marginal cost curve (EMC). The EMC formulation allows for multi-state and multi-block dispatch of generating units and is used to determine the optimal energy of pumped-storage units. A new approach is developed to compute the first and second derivatives of the expected generation energy of a thermal unit with r...

To address the problems of wind and solar generation volatility lose photovoltaic resources, on basis complementary property wind-solar-water, topology structure wind-solar-water synergy power system is constructed. Taking minimum grid fluctuation index, wind-photovoltaic-hydro discard rate greatest economic effectiveness station as goal functions considering various constraints wind, photovolt...

In this paper an optimal load-frequency controller for a nonlinear power system is proposed. The mathematical model of the power system consists of one area with several power plants, a few concentrated loads and a transmission network, along with simplified models of the neighbouring areas. Firstly, a substitute linear model is derived, with its parameters being identified from the responses o...

This paper deals with automatic generation control of multi area power system using a Fuzzy PID controller. The controller parameters are optimized by Grey Wolf Optimizer (GWO) algorithm. Initially, Hydro-Thermal-Gas two area power systems is considered and superiority of the proposed controller is verified by comparing the results with GWO optimized classical PID controller as well as recently...
