In allusion to the fact that the heavy and inaccuracy workload as well as the problems which are lack of accuracy and practical applicability of model based on conventional component-based approach load modeling, this paper applies the theory of fuzzy C means clustering and pattern recognition, with full use of the power information from consumer side collected by the load control system in power...
Photovoltaic generation (PV) output power varies depending on the time, weather, and season. Especially, PV output power can be low in the night or under bad weather conditions. In these cases, an electric vehicle (EV) battery can serve as a substitute for the storage system, and enables to attain in-house generation power continuously regardless of these bad conditions. In this study, we constructed...
In this paper, we developed an optimal dispatching model of Smart Home Energy Management System (SHEMS) with distributed energy resources (DERs) and intelligent domestic appliances. In order to achieve multi-objective optimization between the saving money and living comfortable, we investigate the math models of various components and come up with the new concept “load value” for quantitative measure...
Aimed at the applied limitations of traditional Spare Power Automatic Switchover inside of substation using in chain-mode grid model,an new technology of Area Spare Power Automation Switchover was researched. The basic theory and process was discussed while the key points also proposed. Through demonstrated the cooperation with traditional Spare Power Automation Switchover, auto-reclosing, security...
Due to the increase new boundary conditions of the distributed generation, distributed storage, diversity of load and user demand side response in smart distribution park, the traditional park planning method, integrated technology and operation control technology is no longer to adapt to the new requirements. According to analysis the implementation key technology of smart distribution park, give...
A building energy consumption model is presented. The purpose of the model is to provide a test bed to develop Dynamic Load Control (DLC) algorithms and investigate the implications of these to humans in office buildings. The idea of Dynamic Load Control is to manage loads in such a way that the power available from unpredictable sources can be utilized most effectively. In the case of buildings,...
For the sake of accurate energy resource allocation in smart buildings with hybrid solar energy and main electrical grid, an uncertainty-aware minority-game based energy management system (UAMG-EMS) is introduced in this paper. Multiple agents are deployed in the building, and are able to consider two types of uncertainties: (i) stochastic noise from energy meters/sensors; and (ii) uncertain working...
Many automatic systems of electric power system, such as, Energy Management System (EMS), Tariff Meter System (TMS), etc, usually have separate data model that it's necessary to achieve resource sharing and data integration of these automatic systems. This paper introduces the research and development of distributed data integration query system based on CORBA which integrates the real-time data that...
To provide the real-time application environment in the laboratory for the research of on-line analysis and control applications in EMS system, a simulation platform used for system-level closed-loop control experiment is proposed and realized based on RTDS and EMS in this paper. A protocol converter and a real-time data storage control generator are developed independently. Through the RTDS-GTNET...
