A Black-Box Dynamic Equivalent Model for Microgrids Using Measurement Data
A dynamic equivalent black-box model, based on Prony analysis is presented in this paper. The proposed model is suitable for dynamic studies of microgrids, considering changes in the active and reactive power, bus voltages, currents and frequency. The developed model is evaluated using simulation results obtained from a medium voltage microgrid and test measurements recorded in a low voltage mi...
متن کاملSnow water equivalent estimation using blackbox optimization
Accurate measurements of snow water equivalent (SWE) is an important factor in managing water resources for hydroelectric power generation. SWE over a catchment area may be estimated via kriging on measures obtained by snow monitoring devices positioned at strategic locations. The question studied in this paper is to find the device locations that minimize the kriging interpolation error of the...
متن کاملCombining time DEA scores using a dynamic panel data model
We define a combined DEA score to evaluate efficiency in agricultural research. The production model we propose considers efficiency measurements under variable returns to scale for each year in the period 2012–2017. We postulate a first-order autoregressive process in the presence of covariates, to explain efficiency. Powers of the autocorrelation coefficient estimated assuming a dynamic panel...
متن کاملDynamic Equivalent Modeling of a Grid-Tied Microgrid Based on Characteristic Model and Measurement Data
Microgrids can significantly improve the utilization of distributed generation (DG) and the reliability of the power supply. However, in the grid-tied operational mode, the interaction between the microgrid and the distribution network cannot be ignored. The paper proposes an equivalent modeling method for the microgrid under grid-tied mode based on a characteristic model. It can simplify the m...
متن کاملRevenue - Profit Measurement in Data Envelopment Analysis with Dynamic Network Structures: A Relational Model
The correlated models are introduced in this article regarding revenue efficiency and profit efficiency in dynamic network production systems. The proposed models are not only applicable in measuring efficiency of divisional, periodical and overall efficiencies, but recognizing the exact sources of inefficiency with respect to revenue and profit efficiencies. Two numerical examples, consisting ...
