This work presents a novel Anti-Islanding (AI) protection of Photovoltaic (PV) Systems based on monitoring the dc-link voltage of the PV inverter. A PV System equipped with AI protection like frequency relays, a rate of change of frequency (ROCOF) relay, and respectively the proposed dc-link voltage relay is simulated under the conditions of islanding and the detection time for all these AI techniques are compared. The study shows under which conditions our proposed dc-link voltage AI relay is the most efficient.
1. Open the "Banu_PVarray_Grid_det_AI_UPEC2014.slx" file with Matlab R2014a or a newer Matlab release. 2. Open the "Relay Protection Bus B20 (20 kV)" block to see the Anti-Islanding Protection Scheme, including the new "DC-Link Voltage Protection" Method and its settings.

This work presents a Matlab/Simulink study on anti-islanding detection algorithms for a 100kW Grid-Connected Photovoltaic (PV) Array. The main focus is on the islanding phenomenon that occurs at the Point of Common Coupling (PCC) between Grid-Connected PV System and the rest of the electric power system (EPS) during various grid fault conditions. The Grid-Connected PV System is simulated under the conditions of islanding, and anti-islanding (AI) relay reaction times are measured through the simulation.
1. Open the "Fault3_50Hz_Banu_PVarray_Grid_IncCondReg_det_AI_2013_.slx" file with Matlab R2013b or a newer release to simulate the 100kW Grid-Connected PV Array (Detailed Model) with Anti-Islanding Relays. 2. To see the Anti-Islanding Protection Relays and its settings, open the "Relay Protection Bus B20 (20kV)" block.

This work aims to implement in Matlab and Simulink the perturb-and-observe (P&O) and incremental conductance Maximum Power Point Tracking (MPPT) algorithms that are published in the scientific literature.
1. Open the .slx file (PVArray_DC_DC_Buck_MPPT.slx) in Matlab 2012b or a newer version. 2. Default settings of "PVArray_DC_DC_Buck_MPPT.slx" Simulink model are given in Model Proprieties: File -> Model Proprieties -> Model Proprieties -> Callbacks -> PreLoadFcn* as follow: load('25PVArrayExperimentalData.mat'); MPPT_IncCond=Simulink.Variant('MPPT_MODE==1') MPPT_PandO=Simulink.Variant('MPPT_MODE==2') MPPT_MODE=1 Constant_800=Simulink.Variant('Irradiance_Mode==1') Constant_1000=Simulink.Variant('Irradiance_Mode==2') Step=Simulink.Variant('Irradiance_Mode==3') Irradiance_Mode=2 3. To run the "PVArray_DC_DC_Buck_MPPT.slx" Simulink model with P&O algorithm activate "MPPT_PandO=Simulink.Variant" at the Matlab command prompt by setting the "MPPT_MODE" with "2": "MPPT_MODE=2". Use the same procedure to change "Irradiance_Mode". To simulate the PV Array at 70°C use the command: "load('70PVArrayExperimentalData.mat');" *For more details about Variant Subsystems see the Matlab Documentation: https://www.mathworks.com/help/simulink/examples/variant-subsystems.html

This work presents the performance evaluation of incremental conductance maximum power point tracking (MPPT) algorithm for solar photovoltaic (PV) systems under rapidly changing irradiation condition. The simulation model, carried out in Matlab and Simulink, includes the PV solar panel, the dc/dc buck converter and the MPPT controller. This model provides a good evaluation of performance of MPPT control for PV systems.
Open the MDL files in Matlab 2014a or a newer version.

Costas arrays are permutation matrices that meet the added Costas condition that, when used as a frequency-hop scheme, allow at most one time-and-frequency-offset signal bin to overlap another. Databases to various orders have been available for many years. Here we have a database that is far more extensive than any available before it. A very powerful and easy-to-use Windows utility with a GUI accompanies the database.
Download the file GetStarted.zip. This file contains the Instructions as a PDF file, the extraction and analysis utility in its own ZIP file, and several information files includign an enumeration database in an Excel file.
Unpack this file in a folder that you want to be the location of your Costas array database. Be sure and unpack subfolders, so that you dee subfolders /Searches and /Generated when you are done. Folder /Searches contains all Costas arrays to order 29, and folder /Generated contains all generated Costas arrays to order 100. The file Read_CA_Database_00.zip contains the extraction and analysis utility. It may be extracted in-place or, if the database is on a network drive or other location inconvenient for DLLs, in its own folder anywhere on a local drive such as your C:\ drive. See the Instructions PDF for details.
Then, as you need them, add these files: CA_Database_101-200.zip More data for /Generated folder CA_Database_201-300.zip More data for /Generated folder CA_Database_301-400.zip More data for /Generated folder CA_Database_401-500.zip More data for /Generated folder CA_Database_501-600.zip More data for /Generated folder CA_Database_601-700.zip More data for /Generated folder CA_Database_701-800.zip More data for /Generated folder CA_Database_801-900.zip More data for /Generated folder CA_Database_901-950.zip More data for /Generated folder
CA_Database_951-1000.zip More data for /Generated folder CA_Database_1001-1030.zip More data for /Generated folder
This is a file that was produced by the extraction/analysis utility FrHop_LUB_Database.zip Frequency hop LUB list; useful with PLL-based waveform generators
For further information, see the file Costas Arrays to Order 1030 INSTRUCTIONS.pdf

The dataset stores a random sampling distribution with cardinality of support of 4,294,967,296 (i.e., two raised to the power of thirty-two). Specifically, the source generator is fixed as a symmetric-key cryptographic function with 64-bit input and 32-bit output. A total of 17,179,869,184 (i.e., two raised to the power of thirty-four) randomly chosen inputs are used to produce the sampling distribution as the dataset. The integer-valued sampling distribution is formatted as 4,294,967,296 (i.e., two raised to the power of thirty-two) entries, and each entry occupies one byte in storage.
The big dataset file is 4GB in size. The dataset contains 4,294,967,296 entries and each entry occupies one byte in storage. The MD5 checksum is 4ee9 a09a a509 fd70 4152 2fd2 f263 ae25. The SHA256 checksum is d9a4 fb8d d9f0 de29 b1e2 3316 c78d 8e65 4ec7 d60f 7ebc ec9e ee57 6fa2 e392 3b57. Note that the above hash checksum results are displayed in groups of four digits.

HazeRD is an outdoor scene dataset for benchmarking dehazing algorithms. HazeRD contains 10 different scenes based on the architectural biometrics project. For each scene, the ground RGB images, depth maps, and synthesized hazy images following the atmospheric optics are provided; the hazy images come with five different haze level using real life physical parameters. The main features of HazeRD to other dehazing datasets are: HazeRD focuses on outdoor scenes whereas other datasets provide indoor scenes; and, the synthesis is based on real life parameters.

The Million Song Dataset is a freely-available collection of audio features and metadata for a million contemporary popular music tracks. Its purposes are:
- To encourage research on algorithms that scale to commercial sizes
- To provide a reference dataset for evaluating research
- As a shortcut alternative to creating a large dataset with APIs (e.g. The Echo Nest's)
- To help new researchers get started in the MIR field
