Comparison of regimes of active two-port networks with stabilization of load voltages
نویسنده
چکیده
The problem of normalization of circuit regime parameters, choice of characteristic regimes and scale values is considered. Disadvantages of traditional normalization are shown. The method of projective coordinates reveals the characteristic regimes and proves the normalized expressions. The examples of recalculation of regime parameters are given for comparable circuits. The obtained results allow to carry out the analysis and to compare regimes of similar active two-port networks. The given approach is applicable to “flowed” form processes of different engineering areas.

Analysis and Comparison of Load Flow Methods for Distribution Networks Considering Distributed Generation
Conventional passive distribution networks are changing to modern active distribution networks which are not radial. Conventional load flow methods should be modified for new distribution networks analysis. In modern distribution networks distributed generation (DG) units are embedded with conventional and/or renewable resources. DG units are generally modeled as PV or PQ nodes which inject ...

One of the basic components of future distribution networks are renewable energy resources (RER). The uncertainty in power production of renewable resources such as wind and solar as well as load is another characteristic of such networks. Conventional power flow methods as a basic tool for power system studies may not be suitable for active distribution networks such as microgrids. In this pap...
متن کاملA Grid-Connected PV Inverter with Compensation of Load Active and Reactive Power Imbalance for Distribution Networks
Load balancing is an important issue in distributed systems. In addition, using distributed generation sources such as photovoltaic is increasing. Power electronic converters are main interfaces between the sources and the grid. In this paper, a method has been proposed to reduce the load imbalancing in distribution networks using PV Grid Interface Converter. Two DC/DC and DC/AC converters have...
متن کاملImproving the performance of UPQC under unbalanced and distortional load conditions: A new control method
This paper presents a new control method for a three-phase four-wire Unified Power Quality Conditioner (UPQC) to deal with the problems of power quality under distortional and unbalanced load conditions. The proposed control approach is the combination of instantaneous power theory and Synchronous Reference Frame (SRF) theory which is optimized by using a self-tuning filter (STF) and without us...
متن کاملImproving the resilience of active distribution networks by optimal charging/discharging management of electric vehicles in parking lots
In the event of a severe incident with a high impact and low probability of occurrence, distribution networks may be separated from upstream networks and several feeders may be disconnected simultaneously within the distribution networks. In such circumstances, to maximize the resilience of the distribution networks and to prevent long-term global outages, they are reconfigured and islanded to ...
