The deterministic methods generally used to solve DC optimal power flow (OPF) do not fully capture the uncertainty information in wind power, and thus their solutions could be suboptimal. However, the stochastic dynamic AC OPF problem can be used to find an optimal solution by fully capturing the uncertainty information of wind power. That uncertainty information of future wind power can be wel...

Unlike perfect competitive markets, in oligopoly electricity markets due to strategic producers and transmission constraints GenCos may increase their own profit through strategic biddings. This paper investigates the problem of developing optimal bidding strategies of GenCos considering participants’ market power and transmission constraints. The problem is modeled as a bi-level optimizati...

Abstract: In this work, the most common problem of the modern power system named optimal power flow (OPF) is optimized using the novel meta-heuristic optimization algorithm ant lion optimizer (ALO). ALO is inspired by the hunting process of ant-lions in the natural environment. ALO has a fast convergence rate due to the use of roulette wheel selection method. For the solution of the optimal pow...

Optimal power flow (OPF) is the most requisite tool in the power system analysis. The OPF is relatively a difficult constrained optimization problem and broadly solved by conventional as well as modern intelligent methods. In this paper the authors proposed a levy flight spider monkey optimization (LFSMO) algorithm to solve the standard OPF problem for IEEE 30-bus system, which is proposed to i...

This paper presents the integration of the Voltage Source Converted-High Voltage Direct Current model| (VSCHVDC) into a conventional Optimal Power Flow (OPF) formulation. The assembled VSC-HVDC-OPF model is computationally implemented and solved by using the Matlab ® optimization toolbox. In this sense, the development complexity degree of the proposed implementation is equivalent to that requi...

Recently, the widespread use of power system controllers, such as PSS and FACTS controllers, has led to the analysis of their effect on the overall stability of power systems. Many studies have been conducted to allocate FACTS controllers so that they achieve optimal power flow conditions in the context of Optimal Power Flow (OPF) analysis. However, these studies usually do not examine the effe...

FOREWORD Optimal power flow (OPF) calculations are increasingly critical to modern power systems operationcontrol, markets and planning. However, it is still not easy to obtain reliable OPF solutions that are fully usable in practical power systems engineering. Better methods and software are continually being pursued. This paper discusses some of the calculation and solution requirements from ...

This paper concerns the Optimal Power Flow [OPF] in multi machine Power System with UPFC using Genetic Algorithm [GA]. The objective is to minimize the cost of the power system, to enhance the power flow in transmission lines and to maintain the voltages at the buses using UPFC. Using the proposed method, the optimal cost and real power losses of the power system with UPFC is achieved by develo...

This paper presents three efficient approaches for solving the Optimal Power Flow (OPF) problem using the meta-heuristic algorithms. Mathematically, OPF is formulated as non-linear equality and inequality constrained optimization problem. The main drawback of meta-heuristic algorithm based OPF is the excessive execution time required due to the large number of load flows/power flows needed in t...
