The objective of dynamic economic dispatch (DED) problem is to determine the generation schedule of the committed generation units, which minimizes the total operating cost over a dispatch period, while satisfying a set of constraints. The effect of valve-points and prohibited operating zones (POZs) in the generating units’ cost functions makes the DED a(More)
This paper presents a model for a multi-period optimal power flow (MP-OPF) problem which includes offshore wind farm connected to the grid by line-commutated converter high-voltage DC (LCC-HVDC) link. The offshore wind farm is composed of doubly fed induction generators (DFIGs), and the DFIGs capability curve is considered in order to obtain a more(More)
This paper proposes a new model for multi-area dynamic economic dispatch (MA-DED) problem, taking into account hydro-thermal generating units, wind power generation and power pool market, for supplying the overall demand of the system for a given horizon. The uncertainties in wind power generations, energy prices and demand of the system are also modeled to(More)
In power system operation, minimizing the power loss in transmission lines and/or minimizing the voltage deviation at the load buses by controlling the reactive power is referred to as optimal reactive power dispatch (ORPD). ORPD is necessary for secured operation of power systems with regard to voltage stability. In this paper, the nature inspired Big Bang(More)
Optimal reactive power dispatch (ORPD) problem is an important problem in the operation of power systems. It is a nonlinear and mixed integer programming problem, which determines optimal values for control parameters of reactive power producers to optimize specific objective functions while satisfying several technical constraints. In this paper,(More)
The objective of dynamic economic dispatch (DED) problem is to find the optimal dispatch of generation units in a given operation horizon to supply a pre-specified demand, while satisfying a set of constraints. In this paper, an efficient method based on Optimality Condition Decomposition (OCD) technique is proposed to solve the DED problem in real-time(More)
Static Var compensator (SVC) is one of flexible AC transmission system (FACTS) elements mainly used for reactive power and voltage control in power systems. This paper deals with multi-modal electromechanical oscillations damping in the presence of severe disturbances. These oscillations include local modes, interarea modes and inter-plant modes. To enhance(More)
