Symmetrical components of current and voltage are great importance in many applications in power systems such as power quality and power system protection. This paper presents the new adaptive linear combiner (ADALINE) structure for symmetrical components traction and estimation. This structure is deal with multi-output systems for parameter traction/estimation rather than the existing ADALINE which deals only with single output system. The new topology it is called MO-ADALINE is also presented. Finally the paper presents a new processing unit which can estimate symmetrical components from the measured current signals. The advantage of this proposed unit is simple to implement. Simulation results are given to validate the proposed algorithms.

This paper presents the design and construction of a Mobile PV-Wind-Battery-Diesel Hybrid System Prototype for isolated electrification. The system includes a real-time monitoring system and a control unit which can control all components automatically. The design uses a short calculation method and then simulated by Homer program. The mobile unit is considered as a mobility utility for remote areas therefore the unit is constructed in a container unit which can be able to be transferred comfortably. The design has the components as : PV 2 kWp Wind turbine 1 kW Battery 24 kWh and Diesel Generator 5kW. From a long experiment the system can operate as the design and it is working stably to supply power to the load. The paper will describe fully for the design construction monitored data and analysis.

This paper presents distributed STATCOM for controlling voltage in distribution line with wind turbines generations at 48 volts. The connection of wind turbine to distribution systems may affect the voltage quality offered to the consumers. One of the factors contributing to this effect is the rapid variations of the wind turbine output power which cause respective fluctuations in the supply voltage. This paper presents the design control and analysis of a Distributed STATCOM when combined with a wind turbine comprising small variable speed generators in this paper it is shown that the distributed STATCOM controlled via a rotating referent frame: RRF and recursive DFT are simple method to DSP control technique. The result of experiments the STATCOM can improve the transient stability voltage of wind turbine that we have referred the IEEE1159:1995 standard of power quality.

This paper presents the concept prospect and operation of Green Power Zone (GPZ). The GPZ is defined as part of power grid which provides electrical energy with varying quality depends on customer requirement. Different power quality levels in the premium zone can rang from better than normal utility supply to a supply close to an ideal situation. Electrical energy to the zone is supplied through two feeders from two independent substations. The GPZ center is fully equipped with custom power devices namely dynamic voltage restorer (DVR) and distribution static compensator (DSTATCOM) or even unified power quality conditioner (UPQC). The GPZ can also contain a distributed generator (DG) to take care the power interruption situations from the utility. The incoming feeders to the zone can be designed with improved grounding insulation arresters and reclosing. The simulation results are shown the performance of GPZ by using digital computer simulation program.
