in this paper, we investigated the necessity and effects of optimal control methods in the stability and performance of a micro-grid that operates in islanded mode. the micro-gird is consisted of a combine heat and power (chp), a capacitor bank (cb), photovoltaic panel (pv) as power generation sources. in addition, battery and the building electricity and thermal load are placed on the load sid...

In this paper we consider the design of intelligent control policies for water distribution systems. The controller presented in this paper is based upon a hybrid system that utilizes dynamic programming and rules as design constraints, to minimize average costs over a long time horizon under constraints on operation parameters. The method is very general and is reported here as a controller fo...

this paper describes how multi-agent system technology can be used as the underpinning platform for voltage control in power systems. in this study, some facts (flexible ac transmission systems) devices are properly designed to coordinate their decisions and actions in order to provide a coordinated secondary voltage control mechanism based on multi-agent theory. each device here is modeled as ...

the aim of this paper is to introduce a new approach for obtaining the numerical solution of singulary perturbed boundary value problems based on an optimal control technique. in the proposed method, first the mentioned equations are converted to an optimal control problem. then, control and state variables are approximated by chebychev series. therefore, the optimal control problem is reduced ...

economists were interested in economic stabilization policies as early as the 1930’s but the formal applications of stability theory from the classical control theory to economic analysis appeared in the early 1950’s when a number of control engineers actively collaborated with economists on economic stability and feedback mechanisms. the theory of optimal control resulting from the contributio...

Abstract In the context of digital transformation power grid, twins, as one key technologies to promote and intelligent development industry, are still in theoretical research stage. Focusing on application twin technology an optimal control strategy for heat pump system (HPS) based is proposed. Firstly, DOE-2 model HPS prediction building load established. Secondly, real-time monitoring data, ...

The intelligent control technology with the traditional control theory formats intelligent compound controller in order to learn from each other and improve the overall advantage of complementary features. Fuzzy PID control neuron PID control, fuzzy sliding mode control, and optimal control of the neural network. This paper discusses the current situation and development of smart composite cont...
