Research On Power Router And Its Applications

Demand-side management is to ensure the operation efficiency and stability ofthe power system. The power router monitors and controls the power load withincontrol region, utilizing one or several management control technology. The proposalof power router is based on the demand-side management ideas, effectively managingpower loads and distributed power resource, is not only to ensure the power quality ofthe power system and improve the overall operation efficiency of the power system,but also to solve the problem of a large number of effective management andutilization of distributed power resource.This paper intends to design an embedded power router system applying forconnection and management of distributed energy resource, in order to optimize thematching of supply and the load, and rationally utilize renewable energy. Maincontributions of this paper are summarized as follows:1. The paper analyzes the access method and management of distributed powerresources at home and abroad, and the research background the power router. Bymonitoring the electrical parameters of power distributed power and electrical load,the power router determines operating status of power distributed power and electricalload, and controls them, to achieve rational usage of distributed power, improvepower quality and the total efficiency of the power system.2. The hardware scheme of the power router is presented, mainly including dataacquisition module, master module, Human Machine Interface module, switch arraymodule. Acquisition module is responsible for collecting the electrical parameters ofdistributed power and power loads, for example, the voltage, the current, the power,the power factor and so on. Power router makes a comprehensive judgment based onthe electrical parameters and the power priority, real-time pricing of variousdistributed power supply and power loads.3. Combined with MAS control, the scheduling principles and the specific controlscheme of the power router in a variety of complex situations are analyzed. And someparameters of distributed power resource and electrical load are measured, in order toestablish an information repository.The power router system can monitor the electricity consumption of each electrical load and distributed power, and establish a corresponding repository.Following the principle of power router scheduling, the power router dispatchmanagement, in order to achieve optimal power load side of the router.
