摘要：This paper reviews the most important ways to improve the reliability of supply of consumers,i.e.the increase in the number of directions of supply,use of grid and system automatic controls,and installation of distributed generation sources.The order of priority of municipal loads in terms of electricity and heat supply continuity is then analysed.The concept of so-called energy mini centres containing important loads and distributed generation sources for the supply of these loads connected to medium and low voltage grids is presented in detail.Practical examples of the distributed generation solutions applied in a Silesian municipality are also given.The reliability of selected objects was evaluated using the NIEZ method developed at the Institute of Power Engineering and Control Systems of the Silesian University of Technology in Gliwice.
