In competitive electricity markets with deep concerns at the efficiency level, demand response programs gain considerable significance. In the same way, distributed generation has gained increasing importance in the operation and planning of power systems. Grid operators and utilities are taking new initiatives, recognizing the value of demand response and of distributed generation for grid reliability...
Propose a solution containing distributed power distribution network reconfiguration method, the method with the minimum network loss as objective, the capacity to determine the optimum islanding system, and the remaining network reconstruction, to achieve minimum power load and less power loss. According to the reconstruction of the switch impact factor, correction of islanding scheme, thereby obtaining...
Integration of renewable energy resources into the electricity network is one of the strategies for overall emission reduction in the network. The quantification of emission offset from renewable distributed generation (DG) needs to be incorporated in planning to assess the effectiveness of integrating these resources from emission reduction perspective. In this paper, a numerical method is proposed...
This paper describes the application of the smart medium to low voltage transformer to increase the flexibility of distribution networks, support the accommodation of distributed generation and to attenuate the voltage fluctuations originating from medium voltage network. The theoretical framework is set and three possible control strategies are investigated and their performance to mitigate voltage...
A `smart microgrid' refers to a distribution network for electrical energy, starting from electricity generation to its transmission and storage with the ability to respond to dynamic changes in energy supply through co-generation and demand adjustments. At the scale of a small town, a microgrid is connected to the wide-area electrical grid that may be used for `baseline' energy supply; or in the...
As penetration level of distributed generation (DG) is increasing in distribution networks; new players are introduced into the markets which significantly increase the uncertainties in the system. The concept of Virtual Power Plants (VPPs) is a practical approach to deal with increased uncertainty and complication in future power systems. In such situation, a distribution network is no more passive...
The current feed-in tariff system for renewable energy sources and cogeneration in Croatia stimulates privileged producers exclusively for electricity delivered into the grid, both on transmission and distribution levels. Hence, the electricity consumed on the power plant site is not stimulated by the current feed-in tariff system. Therefore, most privileged producers, in order to receive incentives...
With the continuous effort of exploiting wind energy, a higher penetration of wind power will be integrated into networks in the form of distributed generation. In order to well plan the integration of wind power and the network, the randomness of wind power as well as its influence to the whole distribution networks should be considered. As a result, traditional optimal planning approach for distribution...
Increasing complexity of interconnected electricity grids with a high integration level of dispersed generators leads that ldquobusiness as usualrdquo operating modes and regular devices in distribution networks are not efficient enough to ensure the centralized management of a large amount of information and high-level functionalities (advanced distribution automation-ADA) for future electricity...
