Title: Distributed Electrical Energy Systems: Needs, Concepts, Approaches and Vision (in Chinese)

Abstract

Intelligent distributed electrical energy systems (IDEES) are featured by vast system components, diversifled component types, and difficulties in operation and management, which results in that the traditional centralized power system management approach no longer flts the operation. Thus, it is believed that the blockchain technology is one of the important feasible technical paths for building future large-scale distributed electrical energy systems. An IDEES is inherently with both social and technical characteristics, as a result, a distributed electrical energy system needs to be divided into multiple layers, and at each layer, a blockchain is utilized to model and manage its logic and physical functionalities. The blockchains at difierent layers coordinate with each other and achieve successful operation of the IDEES. Speciflcally, the multi-layer blockchains, named 'blockchain group', consist of distributed data access and service blockchain, intelligent property management blockchain, power system analysis blockchain, intelligent contract operation blockchain, and intelligent electricity trading blockchain. It is expected that the blockchain group can be self-organized into a complex, autonomous and distributed IDEES. In this complex system, frequent and in-depth interactions and computing will derive intelligence, and it is expected that such intelligence can bring stable, reliable and efficient electrical energy production, transmission and consumption.

  • About 4% of the GNP in the US is lost each year due to the degradation of materials. About one seventh of this total could be avoided if best available corrosion control and prevention methods were used. Research on improved materials, control and prevention methods, test methodology, experimentation, and data dissemination could lead to an even greater impact on this loss, which in 1982 was estimated to be over $120 billion. A workshop was held to identify some of the research needs for corrosion control and prevention in energy conservation systems. Other objectives were to determine if the Government couldmore » play a significant role in coordinating the materials-related research and to prioritize the research needs. In Part I, the problem is defined for selected sectors of the economy. In Part II, research needs are discussed, categorized, and prioritized as to their urgency, impact, potential for successful resolution, and contribution to the existing technology data base. The findings were used to help formulate the recommendations of the Corrosion Panel of the Committee on Electrochemical Aspects of Energy Conservation and Storage. The latter was organized under the auspices of the National Materials Advisory Board, Commission on Engineering and Technical Systems of the National Research Council. 2 references, 4 tables.« less
  • This paper presents first a review of the conventional active and reactive power theory, valid for the steady-state analysis and then the instantaneous power theory, introduced by Akagi et al is presented. This instantaneous theory is, valid for steady-and-transient states and for generic voltage and current waveforms. Some examples explaining the physical meaning of the new concepts will be presented. Also, by using the well known concepts of symmetrical components together with the new theory the powers in an unbalanced system will be analyzed, including the zero-sequence instantaneous power. An example will be presented showing how this theory can bemore » used to design and control an active power filter. Some simulation results are presented and discussed.« less
