This paper deals with the performance of fourteen bus systems with and without STATCOM using five level inverter VSI circuit. The VSI is extremely fast in response to reactive power change. A Static Compensator (STATCOM) is a device that can provide reactive support to a bus. It consists of voltage source inverters connected to an energy storage device on one side and to the power system on the other. STATCOM is a device which can supply the required reactive power at low values of bus voltage and can also absorb active power if it has large energy storage. It also required having less harmonic contents in the output and higher compensation VA capacity. When the reactive power of the load is changing continuously, a suitable fast response compensator is needed. STATCOM, TCTC, UPFC, TCSC, SVC are the compensators belonging to FACTS devices. Models for the STATCOM is developed using MATLAB simulink. The simulation of the STATCOM is performed in the Simulink environment and the results are presented.
It is very important to determine the loading of distribution network because it helps in distribution system planning and network reconfiguration etc. In this paper enhancement of maximum loading of radial distribution feeders using genetic algorithm is proposed. The enhancement is done by the optimal conductor selection of radial distribution system. The effect of load models on the enhancement of maximum loading is also investigated. The load growth period is also considered in the investigation. With the proposed method optimal set of conductors are selected by maintaining acceptable voltage limits and current carrying capacity of the feeders. The effectiveness of the proposed method is illustrated with 32-node practical radial distribution system. The proposed method will reduce the real and reactive power losses and also improves the voltage profile.
The main intention of Bidding strategies is to run the system in free and fair manner with desired quantity of power to the consumer’s at most economical price through safe, secure and reliable operation of the power system. Bidding arrangement is properly designed in every country to take care of other abuse of market; these arrangements are kept on changing from time to time depending on the requirement for transparent and non-discriminatory electricity market. In this paper Bidding Strategy of Indian Power Markets, important Key Issues, Electricity Act’s and Challenges in this field are analyzed and also explain about calculation of MCP (Rs/MWh) and Volume (MW) with the help of IEX on-line data.
This paper presents a new methodology for enhancing the distribution system performance by minimizing both technical and non technical losses. Most of the utility companies in developing countries are victims of major revenue losses due to technical and non technical energy losses. The non technical losses are like electricity theft, unauthorized connections, irregular billing and the technical losses are I2R power losses. These losses affect the quality of supply in terms of voltage magnitude, and more tariffs imposed on genuine customers. To improve the efficiency of supply, one of the recommendations is “Boosting the distributor phase voltage, say from 100% to 152% that is, 230V to 350V and stepping down to normal operating voltage (230V) at the consumer premises by using a special voltage regulator device”. The methodology can reduce the technical and non technical losses in the electrical distribution system up to 36.12% of total power supplied to electrical distribution system. Hence the voltage profile can be improved by reducing the I2R losses. As the normal operating voltage of any home appliances is 230V, in the proposed methodology the electrical distributor phase voltage is maintained up to 350V.So if any domestic consumer tries to get unauthorized/illegal power tapping connection, the home appliances are get damaged due to over voltage. Hence, with this approach there is no chance for power theft or unauthorized connections in the distribution system. When the electrical distributor operates with more voltage than the normal operating voltage, the I2R losses in the distributor will be reduced considerably.
This paper presents simulation and hardware implementation of Load compensation by using DSTATCOM. This proposed DSTATCOM systems includes 1/z controller algorithm for control the system. Contributions are made in several aspects of the whole system, including inverter design, system simulation, controller programming, and experimental setup. The algorithm used for Load compensation by using DSTATCOM is the 1/z controller algorithm. In this method the error current can be measure and compare with reference current to achieve maximum power quality and maximum power deliver to source to load. The DSTATCOM consists of a inverter circuit, which is supposed to operate as the main part of the system, a three phase inverter is used. It provides the opportunity to have either higher or lower output voltage compared with the output. The resultant system is capable of load compensation by using DSTATCOM and obtained high power quality. The 1/z controller algorithm is used to compare error current with reference current and gives gate pulses to the inverter circuit. MATLAB and Simulink were employed for simulation studies. Experimental results indicate the feasibility and improved functionality of the system.
