This paper proposes an Approximate Dynamic Programming (ADP) based approach for solving the long-term renewable generation expansion planning problem by considering the effects of hourly security-constrained unit commitment (SCUC). Compared with traditional approaches, the proposed approach can assist Independent System Operators (ISO) to determine the dynamic expansion for multiple years on the basis...
A detailed operation simulation based planning alternative evaluation method of power system with large-scale wind power is proposed in this paper, since the traditional power system planning evaluation methods are not applicable because of the intermittent and uncertainty of wind power. The evaluation framework of this method is established with power system operation simulation in the chronological...
As the penetration of variable renewable generation increases in power systems worldwide, planning for the effects of variability will become more important. Traditional capacity adequacy planning techniques have been supplemented with integration studies, which have been carried out in power systems with high targets for renewable generation. These have highlighted the increased variability that...
A discussion of the technical analysis and results (including both steady state/reliability and economic components) for a study spanning a broad portion of the country will be presented. This paper will include analysis of and commentary on the performance of three extra high voltage classes and their applicability for large-scale, long distance energy delivery. Finally, a discussion of the challenges...
Power planning engineers are trained to design an electric system that satisfies predicted electrical demand under stringent conditions of availability and power quality. Like responsible custodians, we plan for the provision of electrical sustenance and shelter to those in whose care regulators have given us the responsibility to serve. Though most customers accept this nurturing gladly, a growing...
The Pareto ant colony algorithm (PACA) for multi-objective power network planning is presented according to the current situation of resolve multi-objective power network planning by translate multi-objective problem to single-objective problem. The weights are determined randomly for each objective, make all the objective have the same status and avoid the difficulty of determine weights. It can...
When there are transmission service requests for a specific sink/source pair in a transmission system, the ISO must allocate the ATC of that pair to the requests. Since the requests could have different types, tariffs and time frame, the allocation must be accomplished in a sound and fair manner that considers various aspects of the requests. This paper proposes an approach to allocate the ATC to...
The blackout has become worldwide concerned problem. We focus on the aspects of causes and restoration. In this paper, we reviewed the blackout in Hainan Island power system and analyzed the causes and restoration procedure. Some experience was summed. At last we put forward to some exposed problem and gave some suggestion.
Reliable operation of power system is fundamental to the on-going industry reform. This paper presents the result of marginal power flow evaluation performed on Korean power system for planning mode. It uses two commercial software packages: physical and operational margins (POM V. 2.2) and probabilistic reliability assessment (PRA V. 3.1), respectively. The case studies of Korea power system for...
