This paper presents the implementation of distributed controls in a microgrid operation. The approach utilizes the advantages of using Multi Agent Systems technology for controlled operation of a microgrid. The auctioneer aims to optimize the operation of the microgrid by optimizing the production of local distributed generators. An artificial immune system based algorithm is applied on a typical...
The share of distributed generation (DG) in the power system generation is increasingly grown up and for the economical and technical reasons; their integration is deeply concentrated by the researchers. This paper reintroduces the integration of distributed energy resources (DER), i.e. DGs, controllable loads and energy storages, into micro grid and virtual power plant (VPP) and also reviews their...
The presence of distributed generation poses new challenges in the management and operation of electrical grids. Distributed generation (wind, combined heat and power, etc.) already accounts for 20% or more of total generation in some electric utilities and this figure is constantly increasing worldwide. TSOs, DSOs and energy markets need to have some visibility on a large number of small power injections...
After analyzing typical structure of microgrids with distributed energy sources, a new idea of microgrid based on "DC energy pool" is proposed in the paper, whose energy exchanging process is also discussed. The new idea lays stress on the skillfully control of energy stored in the energy-storage device. Since the power balance within the microgrid is realized in a way with the help of distributed...
The following topics are dealt with: system wide events; energy resources; new technologies; power reliability; quality and safety; measurement and control; market structures; wind power; nuclear power; distributed generation; smart grid; vision for 2020.
The unbundling of power systems and the emergence of electricity markets favor the deployment of distributed generation in electricity networks. Microgrids are low-voltage distribution networks comprising micro-generation, storage devices and controllable loads that can operate interconnected or isolated from the main distribution grid as a controlled entity. This paper proposes a new method, based...
