Proper Solutions

The enormous growth in the renewable energy sector has shown tremendous improvement in the energy sector which also paves the way for huge transmission traffic in transmission and distribution networks. In addition to this transmission traffic, misbehavior also happens in energy transmission and distributions. The reactive power compensation failure results in power block out. This paper provides proper solutions for compensating reactive power with help of STATCOM and its control strategies. The power quality had been improved with help of various control strategies, PWM variations, Apply Algorithm are efficient methods.

The Ideal

A conquest for Science and also Technology and also the ever-growing planet of innovation trigger numerous innovations. Currently India demandingly picking to beat non-renewable fuel sources sparsity issues along with Renewable Energy Sources (RES). Renewable Energy Sources needs intricate innovations for the usage. Renewable resource resources and also modern technologies possess prospective to supply options to the enduring electricity troubles being actually experienced due to the establishing nations. The renewable resource resources like wind power, solar power, geothermal power, electricity, biomass electricity and also energy tissue innovation may be made use of to get over electricity lack in India. To overcome the power demand for such a fast-growing economic climate, India will certainly need an ensured source of 3- 4 times extra power than the overall power consumed today. This work reviews different control techniques and proposes a new control technique Optimal Recurrent Neural Networks (ORNN) based Controller to mitigate the power quality (PQ) disturbances of power system. In the proposed approach, optimal weight selection is employed for enhancing the learning procedure of RNN (ORNN). Here, ORNN technique is utilized for selecting the ideal control signal of grid inverter through optimal adjustments of the control variables in the power system. The proposed strategy creates the ideal control of the grid inverter which tries to enhance the power quality of a power system and manage the line voltage by providing reactive power compensation. This paper reviews several papers with different control strategies applied to the grid connected inverter.

Transmission And Distribution

In a deregulated electric service environment, an effective electric transmission and distribution networks are vital to the competitive environment of reliable electric service. Power quality (PQ) is an item of steadily increasing concern in power transmission and distribution. The traditional approach to overcoming capacity and quality limitations in power transmission and distribution in many cases is the addition of new transmission and/or generating capacity. This, however, may not be practicable or desirable in the real case, for many of reasons. From technical, economical and environmental points of view, there are two important - and most of the time combined - alternatives for building new transmission or distribution networks to enhance the transmission system capacity, and power quality: the Flexible alternating current transmission devices and controllers, and the distributed generation resources near the load centers. The connection of distributed generation to the distribution grid may influence the stability of the power system, i.e. angle, frequency and voltage stability. It might also have an impact on the protection selectivity, and the frequency and voltage control in the system. This paper presents a low cost FACTS based Dynamic Distribution System Compensator (DDSC) scheme for voltage stabilization and power transfer and quality enhancement of the distribution feeders connected to a dispersed wind generator, using MATLAB/ SimPower System simulation tool.

The use of automation and energy efficient equipment with electronic control would greatly improve industrial production.  These new devices are more sensitive to supply voltage deviation and the characteristics of the power system that was previously ignored are now very important. Hence the benefits of distribution automation have been widely acknowledged in recent years. This paper proposes an efficient load flow solution technique extended to find optimum location for reactive power compensation and network reconfiguration for planning and day-to-day operation of distribution networks.  This is required as a part of the distribution automation system (DAS) for taking various control and operation decisions.  The method exploits the radial nature of the network and uses forward and backward propagation technique to calculate branch currents and node voltages.  The proposed method has been tested to analyze several practical distribution networks of various voltage levels and also having high R/X ratio.
