Power Generating Equipment

Consequent to power sector reforms, customers' satisfaction is gaining vital importance at power distribution companies. Customers are now getting a choice of choosing their electricity supplier as well as options of investing in their own power generating equipment. The threat of losing customers is driving power distribution companies towards ensuring customer satisfaction. Apart from availability of electricity supply on a 24 / 7 basis, electricity customers now expect ease in getting new electricity connection, advice on most suitable category of supply, timely meter reading, billing, and handling of grievance. To provide customers with great satisfaction, power distribution companies have to give quality attention to offering excellent services that attracts customers and clear up all customers' complaints. Frontline managers play a very significant role in the electric utility companies. They act as an inter-face between the customers / public and the company. This chapter attempts to elaborate customers' expectations from the frontline managers in power distribution companies.

The Cost

Plug-in hybrid electric vehicles (PHEVs) have the potential of substantially reducing petroleum consumption and vehicular CO2 emissions relative to conventional vehicles. The analysis presented in this article first ascertains the cost-effectiveness of PHEVs from the perspective of the consumer. Then, the potential effects of PHEVs to an electric utility are evaluated by analyzing a simplified hypothetical example. When evaluating the cost-effectiveness of a PHEV, the additional required premium is an important financial parameter to the consumer. An acceptable amount for the additional upfront costs will depend on the future costs of gasoline and the on-board battery pack. The need to replace the on-board battery pack during the assumed vehicle lifetime also affects the allowed premium. A simplified unit commitment and dispatch model was used to determine the costs of energy and the CO2 emissions associated with PHEVs for different charging scenarios. The results show that electricity can be used to charge PHEVs during off-peak hours without an increase in peak demand. In addition, the combined CO2 emissions from the vehicles and the electric generation facilities will be reduced, regardless of the charging strategy.

Charging Stations

The electric vehicle (EV) is one of the most important and common parts of modern life. Recently, EVs have undergone a big development thanks to the advantages of high efficiency, negligible pollution, low maintenance, and low noise. Charging stations are very important and mandatory services for electric vehicles. Nevertheless, they cause high stress on the electric utility grid. Therefore, renewable energy-sourced charging stations have been introduced. They improve the environmental issues of the electric vehicles and support remote area operation. This paper proposes the application of fuzzy control to an isolated charging station supplied by photovoltaic power. The system is modeled and simulated using Matlab/Simulink. The simulation results indicate that the disturbances in the solar insolation do not affect the electric vehicle charging process at all. Moreover, the controller perfectly manages the stored energy to compensate for the solar energy variations. Additionally, the system response with the fuzzy controller is compared to that with the PI controller. The comparison shows that the fuzzy controller provides an improved response.
