“…A multifaceted system evaluation is required in order to implement such novel power distribution concepts. For example, there have been studies of supply reliability with consideration of cooperation between system power supply and DGs [4], or of multiple-quality power supply [5]. There are also reports on the evaluation of supply reliability in terms of interruption cost [6,7], thus placing more emphasis on customer needs.…”

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.

“…In Japan, Flexible, Reliable, and Intelligent Electrical eNergy Delivery System (FRIENDS) has been proposed as an ideal concept by many researchers and engineers for future power distribution system with distributed energy resources (DERs). In addition to the basic concept of FRIENDS, power control scheme, system configurations, wiring methods, and evaluation of reliability and PQ have also been proposed17–24.…”

This paper describes the characteristics and performances of a multiple power quality supply system (MPQSS), which consists of power electronics-based voltage compensators and three types of distributed generators (DGs). Its original concept of a future power delivery system having different service levels to meet each customer or load requirement at the same time was proposed as Flexible, Reliable, and Intelligent Electrical eNergy Delivery System (FRIENDS). The effectiveness of the developed power system was measured during an actual field demonstration conducted in 2007 by the New Energy and Industrial Technology Development Organization (NEDO), Sendai, Japan. Its effectiveness in feeding four classes of alternative current (AC) and one of direct current (DC) power while meeting various customer requirements was confirmed. Some sets of test data and an analysis using the data indicate that the developed system meets all the requirements for DG-related plants and has additional benefits. The power system maintains voltage and frequency conditions without interruption in the every state, grid interconnection, islanding, and backup modes.  of DGs, was developed and installed at a test site in Sendai, Japan. The system's response to different power disturbances was measured and checked during the field demonstration.The first part of the paper explains summary of the concept of the MPQSS, while Sections 3, 4, and 5 describe the performance and test results of the developed quality technologies integrated into one system. The effectiveness of the MPQSS as one of the ideal power systems is described.

“…The authors too have developed a concept of next-generation power distribution system called FRIENDS (Flexible, Reliable and Intelligent ENergy Delivery System) [3]. In FRIENDS, multiple quality control centers (QCC) are installed between distribution substations and customers, and appropriate control of such facilities provides power conditioning [4], multi-quality power supply [5], and other functions. In addition, if these multiple QCCs are connected not only in a power system but also in a heat system, fuel system, and information network, the DG groups can contribute to energy supply to points of demand by interchange of energy and information.…”

SUMMARYRecently, the basic framework of electric power systems has been changed significantly by deregulation of electric power industry. Also, distributed generators (DGs) such as renewable energy generations, co-generations, and energy storage systems have been introduced into the demand sides not only for saving energy and the global environment, but also for compensating voltage drops and supply interruption. In the future power systems, a lot of small-sized DGs will supply the electricity with existing large-scale generators under a competitive environment. In this context, it is desirable that DGs contribute to stable, reliable and economic operations by coordinating with existing large-scale generators. For example, power from large-scale generators could be leveled if DGs are operated during the peak period. Also, ancillary services such as frequency control, voltage control, and supply of reserve capacity could be executed by controlling DGs directly or indirectly. Under these circumstances, the authors have proposed a new power distribution system: Flexible, Reliable and Intelligent ENergy Delivery System (FRIENDS). This paper investigates some kinds of power supply systems which coordinate DGs with existing large-scale generators including the concept of FRIENDS and considering how DGs are managed. The effects of DGs which contribute to supply the energy and/or the reserve in every power system are evaluated.
