The research of residential load aggregation mode and application orienting to energy Internet

The dispersion and real-time variation of the resident load bring some difficulties to the load management. Orienting to the energy internet, Equipment for residential can achieve the load centralized management and unified dispatch as well as using aggregated characteristics to make more effective service in intelligent electric business and demand side management operations. According to the characteristics of residential equipment with the Energy Internet, this paper proposes five kinds of aggregation modes combined with the hierarchy analysis thought and the user of electricity infrastructure. Whats more, this paper makes the studies on the architecture of residential load aggregation system, aggregation modes and key technology. It also analyses the application of load aggregation in intelligent use of electricity, demand side management(DSM) and new energy consumptive and other business.

A residential load identification algorithm based on periodogram for non-intrusive load monitoring

Non-intrusive load monitoring is an important development direction of electric load monitoring. Traditional NILM mainly track and decompose the power voltage current, and other transient or steady-state parameters like power parameters at the monitoring system entrance, and then identify the specific type of load. The load identification method is complicated, and there are limitations on identifying multiple devices switching simultaneously. This paper studied on NILM oriented residential load identification methods and proposed one based on periodogram, and then made the detailed theoretical analysis and simulation verification of the selection and determination of electric appliances characteristic model. This method could greatly simplify the system complexity and improve the efficiency of identification. It offers important reference value for the research on load online monitoring methods in residential domain.

Information interactive model of power grid and user-side devices

In this paper, an information interactive model of power grid and user-side devices is designed, on the basis of studying and practicing smart grid interactive functions. First, block diagram of information interactive system model of power grid and user-side devices is given, and on the basis of it, smart grid user interface system architecture is extracted. Second, the realization process of information interaction is shown with the client/server model, and then the general communication service interface(GCSI) is put forward as well as the functional timing diagram of broadcasting.

The architecture and technology of demand response within Energy Internet

This paper mainly introduces the demand response project and Energy Internet, meanwhile makes a brief introduction of them. We also innovative summed up the demand response use case in the energy network to clarify their relationship. With analyzing current energy network concept, we summarize architecture and technology.

Preliminary study on architecture of global energy internet standard

Global Energy Internet (GEI) is the trend of development of the energy industry with broad prospects and potential economic benefits and social benefits in the world. It is crucial to establish the technical standard system of GEI for technology innovation and industrial development. First, technical standard systems and standards at home and abroad have been combed in the field of ultra-high voltage transmission, smart grid and clean energy. Secondly, brief analyses on economic and social benefit have been analyzed for establishment of the GEI standard system. Through the discussion, the content and methodology of GEI standards system are clarified with clear technical courses. Finally, specific suggestions are put forward for application of the GEI standard system, and the study will make a beneficial exploration for the development of GEI.

Research of self-adjusted scheme for load towards utilization equipment

Nowadays, the construction of Smart Grid in China is getting into a raging state and a period of swift development. At the same time, the characteristics of the power load are changing greatly. In this paper, the research of self-adjusted scheme for load towards utilization equipment is mainly for home users, in order to adapt to the changes in Chinas electric power load characteristics. Focus on family lights, a water heater and an air conditioner, and put forward the self-adjusted principles for their loads, propose a corresponding self-adjusted scheme for load. Through the research, a practical scheme for it could be proposed. Based on it, great enhancement could be made on the facets such as energy saving, the increase of the loading rate, the improvement of power usage efficiency and so on.
