Smart Grid

Conversion loss modeling plays a crucial role in hybrid AC/DC microgrid (MG) energy management (EM). However, accurate calculation of the conversion losses is often very costly. Additionally, existing surrogate models typically rely on fixed-voltage DC buses, leading to excessive voltage magnitudes. To overcome these limitations, we propose surrogate models based on piecewise linear neural networks (NNs) that estimate conversion losses using converter power and variable-voltage DC buses.

This dataset is created by an experimental setup of a DC-PV -Battery-based grid-connected distributed generation system. This dataset is split into four parts such as irradiance, and temperature, which were measured by a meteorological station, and lastly, PV output current and voltage acquired by an inverter. Furthermore, we can have a chance to obtain the output PV power by multiplying current and voltage. The dataset has 288 elements for one day as a time series since the station obtains the data within five minutes. However, the whole dataset has three days of data with 864 elements.

This dataset is created for neural network-based surrogate modeling of the power conversion losses. The dataset includes four sets of data (for AC/DC conversion losses under inversion/rectification moes and DC/DC conversion losses during battery charging/discharging, respectively) for the neural network. The raw data is generated using high fidelity analytical models.

This data provides the simulation parameters and the optimal results of the comprehensive active distribution network (ADN) expansion planning model that includes both wire alternatives (WAs) and nonwire alternatives (NWAs). The primary motivation is to find the optimal sizing and siting of NWAs while considering WAs such that the ADN’s dynamically growing electrical load and electrical vehicle (EV) demand are met while maintaining network limits.

To verify the proposed protection scheme, the simulation model of a six-terminal ring flexible DC distribution system is built in PSCAD/EMTDC , where the rated voltage of the DC line is ±10 kV . The fault inception is set at 0.6 s, the sampling frequency is 10 kHz and the protection data window length is 1 ms. The data set reflects the current and voltage values of each line after standardization
