• Nuclear power plant as a source of electrical energy and heat

  Publication

  • T. Minkiewicz
  • A. Reński

  - ARCHIWUM ENERGETYKI / ARCHIVES OF ENERGETICS - Year 2011

  In this paper certain issues concerning usage of nuclear power plants as sources of not only electric power but also thermal energy will be discussed. For such a solution appeals most of all the need to limit harmful emissions of gases (including CO2) and ashes, which come from the process of burning fossil fuels, as well as the raising demand for network heat and chill. Additionally combined heat and power production brings measurable...

• Multi-Agent Signal Filtering for Electrical Energy Demand Management

  Publication

  • A. Opaliński

  - Year 2015

  Consumers participating in electrical energy Demand Response (DR) programs may be exposed to energy-use related decisions at instants of time which are generally hard to predict. This is especially cumbersome to residential consumers who are less capable of investing in special equipment, or devoting significant time to analyze information and take decisions. To ease residential consumer participation, a multi-agent system proposed...

• Control system for contactless electrical energy transfer with varying air gap

  Publication

  • S. Judek

  - Year 2014

  Inductive power transfer (IPT) is a system by which electrical energy may be transmitted without electrical connection through a large air gap between coils. Systems usually considered in the literature are the ones with a constant air gap. The paper describes the analysis of IPT, which allows for supplying an electrical load in the conditions of slow, in relation to the dynamics of power supply, changes in the dimensions of the...
