This paper deals with the presentation of the emerging framework of the remedial activities since the outsourcing of maintenance and repair activities from the core distribution utility. The focus is set on evaluation of remedial actions timings resulted from this change, using elements of statistical analysis, and on detection of the inter-relationships between various phases of the repair activities...
The paper presents a comparison of the accuracy of several approaches to modelling the annual number of supply interruptions and their duration in a MV municipal cable distribution network when estimating the costs of penalty payments to be paid by the given distribution company to individual consumers as a result of breaching the guaranteed standards of supply continuity.
A cluster system architecture for implementing a load shape strategy for demand side management is presented. Modulation of electricity prices, with time-of-use tariffs, is used for inducing low voltage customers shifting their loads according to load shape strategy objectives. The system has a multilevel cluster structure. Each level of the architecture reflects the philosophy of a fully decentralised...
Under real-time or day-ahead pool-based electricity markets, the implementation of the distribution loss allocation procedures implies an access-pricing framework based on half- hour or hour locational prices. For each consumer and distributed generator it is required to apply an additional charge in the energy price in order to cover the cost of active losses. Since every allocation procedure modifies...
A combined flow-based and a marginal cost approach for identifying and quantifying costs-benefits for distributed generators is presented in this paper. The proposed methodology quantifies the interconnection benefits from a distributed generator in terms of total avoided costs. A fuel cell distributed generator is considered for the analysis and for describing the methodology. The transfer distribution...
Application of wavelet transform technique to high impedance arcing fault detection in distribution networks is presented. Phase displacement between discrete wavelet coefficients calculated for zero sequence voltage and current signals at natural network frequency is tracked. The developed wavelet based HIF detector has been tested with EMTP-ATP generated signals, proving better performance than...
The paper suggests a method for solving optimization problems of management and development of distribution electric networks in terms of uncertainty of initial information. The method allows the enumeration of compared variants on the base of technical and economic indices that are calculated considering not the single value, but several concrete combinations of possible values of initial information...
