This paper proposes a hybrid heuristic optimization method based on genetic algorithm and immune systems to maximize the benefits of distribution network operators (DNOs) accrued due to sizing and placement of distributed generation (DG) units in distribution networks. The effects of DG units in reducing the reinforcement costs and active power losses of distribution network have been investiga...

This paper presents a new method named “Life cycle model” for optimal placement of Distributed Generators in a distribution network. The impact of DG at the distribution level is investigated with an emphasis on active power losses and allocation for minimizing the cost of losses and capacity investment costs simultaneously. An application of the proposed method for a distribution network is pr...

In order to reduce the capacity of active power filter (APF), improve its dynamic tracking speed and anti-disturbance ability harmonic currents, so as better solve problem pollution in medium high voltage distribution network, this article is suitable for networks. The three-phase three-wire injection hybrid (IHAPF) network research object, a fuzzy linear disturbance rejection controller (Fuzzy...

Active distribution networks characterized by high flexibility and controllability are an important development mode of future smart grids to be interconnected with large scale distributed generation sources including intermittent energies. However, the uncertainty of intermittent energy and the diversity of controllable devices make the optimal operation of distribution network a challenging i...

The active network approach allows an individual user to inject customized programs into an active nodes in the network, usually called programmable/active routers, and thus process data in the network as it passes through. As the speeds of network links still increase, and subsequently, the applications’ demands for the network bandwidth increase as well, a single active router is infeasible t...

The region-based method has been applied in transmission systems and traditional passive distribution without power sources. This paper proposes the model of total quadrant security region (TQSR) for active networks (ADN) with high penetration distributed generation (DG). Firstly, TQSR is defined as a closed set all N-1 secure operation points state space ADN. Then, modeled considering constrai...
