The major challenge is to minimize the power consumption by optimizing the operation of several loads without impact in the customer's comfort. For this purpose, the design of an Intelligent Demand Management using Intelligent Systems is presented in this paper. Furthermore a comparative analysis is carried out to evaluate the power consumption performance of some Demand Side Management (DSM) techniques. In this case Direct Load Control (DLC), Load Priority (LP) and Scheduled Programming (SP) are compared with the proposed approach based on Artificial Neural Networks (ANNs). Experimental testing is performed with the consumption data base. The testing results show that energy savings can be achieved through control of the states of various loads.","PeriodicalId":330140,"journal":{"name":"2012 IEEE International Symposium on Alternative Energies and Energy Quality (SIFAE)","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123295754","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}

In the future, wind power is expected to be at least comparable to the conventional power generation systems. Large-scale wind farms will need to be integrated into traditional power grid systems, creating the need to establish technical standards to make this integration feasible. This paper covers the performance comparison of a power system with and without the inclusion of a large-scale wind farm.

Numerical investigations of a model turbine (power coefficient and flow behaviour) were undertaken using developed computational models. Turbine design was studied using a time-accurate Reynolds-averaged Navier-Stokes (RANS) commercial solver (ANSYS-CFX v. 12). A physical transient rotor-stator model with a sliding mesh technique was used to capture change in flow field at a particular time step. A shear stress transport k-ω turbulence model was used to model turbulent features of the flow.

Almost 50% of the installed wind turbines are induction generators. With the increase of induction instead of synchronous generators, electrical networks are experiencing different disturbances, which require permanent transient and small signal stability studies. This article presents an analysis of a small signal stability study in the first wind park installed in Colombia. In this analysis a software VORTEXOFT developed by the authors is used for aerodynamic purposes. A modal analysis and eigenvalues were done considering high level of wind power penetration.

Studies show that demand will continue growing and new schemes for generating power and managing resources should be developed. In the case of the transmission network, some constraints may lead to use plants with high emission levels, and therefore, appropriate planning is key to minimize environmental impact. This work proposes a methodology for solving the Transmission Expansion Planning Problem (TEPP) when emissions of CO2 are considered. The result is an investment plan that leads to the lowest level of emissions by means of a Chu-Beasley Genetic Algorithm (CBGA). An improvement step is carried in the CBGA in order to minimize also the cost of the plan. Non-linear Interior Point Method (NLIPM) is used to generate the initial population and Linear (LIPM) is used to solve the operative problem in the evolutionary process. The approach is validated using the IEEE-24 bus system in order to show its effectiveness.","PeriodicalId":330140,"journal":{"name":"2012 IEEE International Symposium on Alternative Energies and Energy Quality (SIFAE)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116168256","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}
