An interactive-dynamic mechanism conceptualizing the cost and benefit of electric power quality

With the deregulation of the electric power energy market, providing power quality has become a more important concern of both power suppliers and customers. Customers require better quality with the development of digitally controlled facilities. However, there is not a specific infrastructure to motivate the design of the power system to achieve a specified level of electric power quality. This paper discusses a power quality interactive-dynamic control mechanism to conceptualize the cost and benefit of power quality. The basic objective is to provide an engineering infrastructure and procedure that 'gives the right signals' to the power supplier and the customer to balance power quality and cost. A power quality level index vector is utilized in the proposed infrastructure.
