It is of great significance to study the optimization of grid structure considering comprehensive maintenance. In this paper, a mathematical model of optimal planning for comprehensive maintenance of power grid was established. The model can consider various technical measures to meet the comprehensive maintenance of power grid, and consider the operation status of power grid. An optimization model...
With the rapid development and application of distributed generation, more and more attention has been paid to the operation and control technology of the wind storage isolated network system. As a kind of new energy application, the operation of wind storage isolated network system has a great technical advantage in the process of operation. Aiming at the problem of self starting and stable operation...
Urban saturation load is the key index to determine the final scale of power grid development in urban power network planning. The research on urban power load forecasting has important guiding significance and practical value for the construction and planning of urban power network in the future. In this paper, a new method based on the saturated load density was proposed for the prediction of urban...
In the calculation of AC / DC power flow, how to consider the control mode of HVDC transmission system effectively is a problem that must be considered in power system planning and operation. In this paper, based on the principle of equivalent power and AC / DC system alternating decoupling solving, a power flow calculation program is presented. The main control modes of HVDC transmission system and...
In this paper, dynamic behavior analysis was focused on the Hu-Liao HVDC and AC parallel transmission system. The Hu-Liao HVDC project was introduced; Simulation method and mathematic models of AC and DC systems were studied as well as corresponding regulators and controllers. The dynamic performance and the interaction between AC and DC systems during serious disturbance were researched by detail...
The general power flow algorithm incorporating HVDC system can not consider the diversified control mode of HVDC system. Especially in Power System Analysis Software Package (PSASP), the key control parameters of HVDC are definite, which is to the disadvantage of steady state analysis and actual control of HVDC system. In this paper the control method transformation conditions and dealing strategies...
In order to explore deeply electrodynamics mechanism of electro-demulsification, singular water droplet, as study object, in w/o (water-in-oil) emulsion is placed in high steady electric field, and ellipsoidal droplet polarization model is established. By the model, droplet's polarization characteristic and its interrelated affecting factors are analyzed. The mathematic expression of polarization...
