“…Up to now, the economic efficiency and supply reliability of new systems such as FRIENDS and micro grids have been considered separately. However, a final comprehensive evaluation in terms of both reliability and cost is needed [8]. In this study, we consider the individual installation of DGs on the customers' premises (below referred to as the conventional configuration), the FRIENDS configuration, and the micro grid configuration.…”

SUMMARYThe authors have proposed the Flexible, Reliable and Intelligent ENergy Delivery System (called "FRIENDS"), which is a new concept for future power distribution systems. Also, a "micro grid" which is a similar concept to FRIENDS has been developed. In a micro grid, an independent distribution system can be constituted by a number of distributed generators. In this paper, FRIENDS, Micro grid, and conventional distribution systems are compared quantitatively in supply reliability and system cost through time sequential Monte Carlo simulations. In addition, for cost evaluation, interruption costs are included to show risk incurred by unsupplied energy. Finally, the authors search for preferable form with install and operation of distributed generators and network composition according to social cost including interruption cost and system cost.

“…Although there has been no attempt here in Japan or in Europe and the United States, where the liberalization of the electric power sector is well underway, to lower costs by reducing reliability, concerns about lower reliability as a result of liberalization have been voiced [1]. In the United States, there is an increasing need for measures for reliability among both suppliers and customers as a result of large-scale power outages after liberalization.…”

“…Moreover, when economic mechanisms are used actively to maintain reliability, or when services such as reliability differentiated supply [1,2] are introduced, a method to evaluate reliability which can take into consideration economic balance, including the costs versus benefits, is needed.…”

“…With respect to stochastic evaluation methods, use has been attempted in fields in which quantitative evaluation methods have been widely employed, including reliability evaluation for customer contact points, and in the field of distribution systems, and proposals to clarify the relationship between cost and reliability for the quantitative evaluation of supply reliability have been made [1,6,[9][10][11][12][13]. The stochastic evaluation method and quantitative method each have advantages.…”

SUMMARYWith the introduction of the competitive electrical power market, large-scale customers can select electric power suppliers. Customers need to consider not only the economical efficiency but also reliability, to decide the amount of electrical power to purchase. This paper develops an economic electric power purchase strategy for customers focusing on reliability. A bilateral contract model expressing electric power suppliers as generators with a forced outage rate is proposed and introduced to assess potential outage risks of the bilateral contract between an electric power supplier and a customer. The outage-related cost, consisting of potential outage risks and the estimated outage cost, is also proposed and introduced as an index of the reliability on the customer side, and an optimal reliability level of a customer is obtained by using the index. Several numerical examples demonstrate the availability of the proposed electric power purchase decision method and reliability improvement strategies for customers are discussed.

“…Analyses of power system reliability can be subdivided into several groups in terms of factors such as the objects of analysis, analytical methods, and purposes of application. In the recent environment surrounding electric power systems, such as increased numbers of power transactions, frequent transmission congestion, and reduction of transmission investments, the reliability analysis of composite power systems is most important [8]. Furthermore, considering that power system operations will be increasingly important in the effective utilization of existing facilities, operational aspects should be included in analyzing reliability.…”

SUMMARYThis paper describes a new program which analyzes the reliability of composite power systems with consideration of power system operational aspects. It uses the sequential Monte Carlo method and calculates annual risk indices for each load point. The program deals with the system problems involved in load flow, voltage, frequency, and small-signal stability if necessary. The distinctive feature of the program is consideration of power system operation in a sequential manner, such as generation dispatch and system restoration after equipment failure. This makes possible the evaluation of both power system planning and operation from the reliability point of view.
