A Novel Optimal Power Flow for Real-time Application
Under the competitive environments, power companies may calculate optimal power flow (OPF) in many occasions: especially for such real time applications as contingency analysis and congestion management. However, caused by congestions, etc., it is not guaranteed that OPF has the feasible solution in every calculation case. This paper proposes a new optimal power flow calculation model applicabl...
متن کاملHydrothermal Optimal Power Flow Using Continuation Method
The problem of optimal economic operation of hydrothermal electric power systems is solved using powerful continuation method. While in conventional approach, fixed generation voltages are used to avoid convergence problems, in the proposed algorithm, they are treated as variables so that better solutions can be obtained. The algorithm is tested for a typical 5-bus and 17-bus New Zealand networ...
متن کاملThe Real-Time Research of Optimal Power Flow Calculation in Reduce Active Power Loss Aspects of Power Grid
In order to research how to availably reduce the active power loss value in power grid system when the power system is operating, it offers a quantitative research in theory through conceiving the unbalanced losses of power grid system under the overloading bus as the investigative object, and establishing an active power loss mathematical model. It carries out online real-time optimal flow cal...
متن کاملReal-time Implementation of Optimal Power Flow Calculator for HVDC Grids
The aim of the paper is to present the centralized architecture for power balancing management in an HVDC, High Voltage Direct Current, grid connecting different AC areas with high penetration of variable energy resources. Such a centralized high level DC Supervisory Control (DCSC) that functions in slower time scale compared to outer level controller has been evaluated in a real time co-simula...
متن کاملDistributed Real-Time Optimal Power Flow Control in the Smart Grid
Conventionally, power system has a hierarchical control structure including primary, secondary, and tertiary controls. The drawbacks of this hierarchical scheme are manifest: 1) it lacks flexibility and scalability, which is against the trend towards an open access power system; 2) load forecast as the basis of tertiary control could be inaccurate and infeasible, especially in micro-grid for ex...
