“…In [2] the knowledge engineering technology combined with conventional programming, in [3] an operator training simulator was exemplary full integrated of the restoration system as EMS function. In [4] an interactive rule-based system was integrated with power flow programming, it can dynamically generate a new restoration plan when needed. The rule-based system has difficulties in knowledge acquisition and maintenance, so some papers [5,6,7] used CBR to overcome the drawbacks of rule-based system.…”

the basic strategy of case-based reasoning (CBR) is retrieving the most relevant cases and adapting them to fit new situation, and solutions would be stored for future reuse. A conceptual framework for a CBR system to scheme black-start plan is presented. The CBR has a hierarchical structure, cases in abstract level present the general characters of black-start, cases in the detail level include the restoration operations of the plants and substation in the subsystem. Conventional CBR system have had limited in revising ability. We developed "path finding" and "generation ability dispatch" algorithms for detail level case revising, and used qualitative process theory (QPT) to revise the abstract cases, the qualitative process model of black-start also can act as an explaining tool. This paper uses the CBR as the main frame, which combines qualitative analysis and quantitative analysis, and the theoretics research and field experience are well organized in this frame.

“…The excessive charging reactive power generated by transmission lines may lead to sustained overvoltage since the system is in a light-load state [27]. Therefore the reactive power constraint [30] is defined as follows: where, nB is the number of units connected to the restored zone; QBr,max represents the maximum reactive power absorbed by unit r; K1 is reliability coefficient, its value is less than one.…”

Power system restoration after a major blackout is a complex process, in which selection of energising paths is a key issue to realize unit and load restoration safely and efficiently. In general, the energising path scheme made beforehand may not be executed successfully due to the possible faults on the related lines under the extreme system condition, so it is necessary to provide alternative path schemes for system restoration. In view of this, the energising path optimisation based on the minimum cost flow model is investigated, then an iterative searching method for alternative path schemes based on mixed integer linear programming is proposed. The iterative method for alternative path schemes could determine more than one scheme with minimal charging reactive power efficiently. In order to make a comprehensive evaluation of the alternative schemes, an evaluation index set is established, and the method based on similarity to ideal grey relational projection is introduced to achieve the final evaluation. The New England 10-unit 39-bus system and the southern Hebei power system of China are employed to demonstrate the effectiveness of the proposed method. The proposed method can provide more efficient and comprehensive decision support for the dispatchers to select reasonable energising paths.

SUMMARYWith the fast-paced changing technologies in the power industry, new power references addressing new technologies are coming to the market. So there is an urgent need to keep track of international experiences and activities taking place in the field of modern power system restoration problem. This paper gives a bibliographic survey, mathematical formulations, and general background of research and developments in the field of restoration problem for past 35 years, based on more than 150 published articles. The collected literature has been divided into many sections, so that new researchers do not face any difficulty in carrying out research in the area of next-generation restoration problem under any environment.
