Short term load forecasting using Multiple Linear Regression

Abstract: this paper we present an investigation for the short term (up 24 hours) load forecasting of the demand for the South Sulewesi's (Sulewesi Island - Indonesia) Power System, using a multiple linear regression (MLR) method. After a brief analytical discussion of the technique, the usage of polynomial terms and the steps to compose the MLR model will be explained. Report on implementation of MLR algorithm using commercially available tool such as Microsoft EXCELTM will also be discussed. As a case study, historical data consisting of hourly load demand and temperatures of South Sulawesi electrical system will be used, to forecast the short term load. The results will be presented and analysed potential for improvement using alternative methods is also discussed.

Using genetic alghoritm for distributed generation allocation to reduce losses and improve voltage profile

Abstract: This paper presents a method for the optimal allocation of Distributed generation in distribution systems In this paper, our aim would be optimal distributed generation allocation for voltage profile improvement and loss reduction in distribution network Genetic Algorithm (GA) was used as the solving tool, which referring two determined aim; the problem is defined and objective function is introduced Considering to fitness values sensitivity in genetic algorithm process, there is needed to apply load flow for decision-making Load flow algorithm is combined appropriately with GA, till access to acceptable results of this operation We used MATPOWER package for load flow algorithm and composed it with our Genetic Algorithm The suggested method is programmed under MATLAB software and applied ETAP software for evaluating of results correctness It was implemented on part of Tehran electricity distributing grid The resulting operation of this method on some testing system is illuminated improvement of voltage profile and loss reduction indexes

Modelling, simulation and performance analysis of a PV array in an embedded environment

Abstract: Photovoltaic (PV) generation involves the direct conversion of sunlight into electrical energy. In recent years it has proved to be a cost-effective method for generating electricity with minimum environmental impact. Due to the environmental and economic benefits PV generation is now being deployed worldwide as an embedded renewable energy source and extensive research is being performed in order to study and assess the effectiveness of PV arrays in Distributed Generation (DG) systems either as a potential energy source or as energy reserve in combination with other types of distributed energy resources. This paper presents the modeling and MATLAB simulation of a stand-alone polycrystalline PV Array system and investigates load following performance efficiency under various loading and weather conditions as well as suitability with regard to enhancing power supply reliability to critical loads. The modeling of the PV array that has been performed in this research using MATLAB Simulink is based on the calculation of parameters for the Thevenin's equivalent circuit of each cell of the array. The standard double exponential polycrystalline cell model has been adopted for this research with solar irradiance E and ambient temperature T as the input and Thevenin's voltage Vthar and Thevenin's resistance Rthar as the output.

Electrical generation and distribution for the more electric aircraft

Abstract: The aircraft industry is developing the more electric aircraft (MEA) with an ultimate goal of distributing only electrical power across the airframe. The replacement of existing systems with electric equivalents has, and will continue to, significantly increase the electrical power requirement. This has created a need for the enhancement of generation capacity and changes to distribution systems. The higher powers will push distribution voltages higher in order to limit conduction losses and reduce cable size, and hence weight. A power electronic interface may be required to regulate generator output into the distributed power form.

Open data IEEE test systems implemented in SimPowerSystems for education and research in power grid dynamics and control

Abstract: This paper presents three IEEE standardized power system benchmarks developed in SimPowerSystems, a MATLAB/Simulink package. The simulation models can be used for baselining and testing new control techniques and protection algorithms for renewable and micro grids integration studies. Analytical examples as well as static, time domain, and frequency analysis are presented to support the correctness of the implementation. The models are available in MATLAB-Central file exchange for power system education and research worldwide.
