The main objective of the paper is to present an innovative complex approach to distributed generation planning and show the advantages over existing methods. The approach will be most suitable for DNOs and authorities and has specific calculation targets to support the decision-making process. The method can be used for complex distribution networks with different arrangement and legal base. [ABSTRACT FROM AUTHOR]

An approach is proposed to the modelling of wind farms in the electric power system long-term planning. It allows a specialist to perform calculations based on scanty information and offers a set of ready-to-use data for easy, fast, and precise modelling. The authors exemplify the calculations of wind speed probability density and power curves and give an idea for relevant corrections. They also show how to pass from a single wind turbine model to the unified model of multiple wind turbines which would meet the requirements of long-term planning tasks. The paper presents the data on wind farms that are operating in UK and Oceania [ABSTRACT FROM AUTHOR]

The paper analyses the reliability of power supply for a 330/750 kV electrical ring. Consideration is also given to the influence of emergency automatics on the maximum permissible power flows in different electrical connection points of the ring as well as to the application of reliability criterion (N-1) in the case of using the emergency automatics to limit post-accident power flows in these points. The authors discuss the role of operative and technological management in securing the power supply reliability. They also analyze situations with disconnection of major generation units and its influence on the blackout development. [ABSTRACT FROM AUTHOR]
