The work concentrates on performance-index-based algorithms and uses a contingency control variable for precise contingency representation. The ranking is based on the value of the sensitivity of the performance index with respect to the contingency control variable for each outage. The computation of the sensitivities is performed using the very efficient co-state method. Furthermore an approach for improving the accuracy of performance-index-based contingency ranking methods is introduced. This approach is based on state rather than performance index linearization with respect to the contingency variable and it provides more accurate results in contingency ranking and selection. The effectiveness of the proposed method in identifying critical contingencies is illustrated using some small test systems. The ultimate goal is to achieve fast and accurate contingency selection, without having to solve the full load-flow problem for each contingency (as is the current utility practice).","PeriodicalId":101495,"journal":{"name":"Proceedings of the 37th Annual North American Power Symposium, 2005.","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129422051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This change in load causes distribution feeders to be overloaded at sometimes and lightly loaded at others. With this load variation, operating conditions of distribution system also vary. If not compensated well, voltage at different buses goes out of nominal range and real loss on the feeders also increases, leading to high operating cost of the system. However, with the advancement in automation of distribution networks, systems like SCADA have made possible to change the topology of the distribution network in real time for minimizing real loss in the system and for improving voltage profile at the buses. The configuration of the system is changed by changing the status of switches such that load is transferred from heavily loaded feeders to lightly loaded feeders. This paper proposes using ant colony optimization (ACO) for solving reconfiguration problem for loss minimization. Ant system, one of the ACO algorithms, has been implemented in a novel hypercube framework on a 33-bus test system and the results obtained show that ACO performs as well as any other proposed method for loss minimization. In fact, this ACO algorithm found the most optimum solution found so far by any other method proposed in the literature for the 33-bus test system considered.","PeriodicalId":101495,"journal":{"name":"Proceedings of the 37th Annual North American Power Symposium, 2005.","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128500778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

OCP seeks to maximize the net dollar savings resulting from the reduction in power and energy losses less the total costs of capacitors. The distribution feeder typically consists of a main branch, some lateral branches, and nodes. Nodes are points on the feeder where segment characteristics change and where electrical loads are connected. This paper presents a new OCP method that employs a branch-and-bound algorithm, which seeks to reduce the total number of possible alternative sizes and sites to test. The proposed method automatically generates combinations of capacitor banks and feeder nodes, it performs power flow analysis to determine the effectiveness of each combination, and it stores the optimal and near-optimal solutions. The switching of capacitors is based on a user-specified power level. The proposed method has been applied successfully to a test distribution feeder. The proposed method has a fast computational time because it does not require evaluating all possible alternative combinations.","PeriodicalId":101495,"journal":{"name":"Proceedings of the 37th Annual North American Power Symposium, 2005.","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121545008","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
