Day-ahead scheduling of a photovoltaic plant by the energy management of a storage system

Abstract

Abstract-The paper discusses and describes a system for energy management of a 10 kW PV plant coupled with a 15 kW -190 kWh storage system. The overall idea is, by knowing the meteorological forecast for the next 24h, to dispatch the PV system and to be able to grant the scheduled hourly energy profile by a proper management of the storage. Due to forecast inaccuracies, the energy manager controls the storage in order to ensure that the plan for hourly energy production is respected, minimizing the storage itself usage. The experimental study is carried out in SYSLAB, a distributed power system test facility at DTU Risø Campus and part of PowerLabDK. Both the PV and the storage are connected to the local network and are fully controllable through the SCADA system. The control management and the models are implemented in MatlabSimulink, which can be interfaced with SYSLAB.

Influence of realistic EV fleet response with power and energy controllers in an EV-wind virtual power plant

“…4 shows the structure of the controller. The considered EC was derived for systems including stationary BESS and RES [1,2,18], and this is its first application to EV fleets. Therefore, the EC sets the I set to each EV based on RES energy production deviations from the forecasted energy plan.…”

“…The EC was equipped with a fixed stiffness control logic in previous articles [1,2,18], meaning that points U and L in Fig. 5 had a manually predefined position along the ordinates.…”

Wind and Photovoltaic Large-Scale Regional Models for Hourly Production Evaluation

“…3, in which the equations for the description of the movement of the sun and the energy conversion chain are implemented. The latter takes in account the conversion process used to evaluate the AC power injected in the grid starting from the DC power produced by the PV modules [19], [20].…”

Testing of a Predictive Control Strategy for Balancing Renewable Sources in a Microgrid

“…4, is formed by several blocks, where the equations for the description on the movement of the Sun and the evaluation of the efficiency chain in the energy conversion process of the PV module, starting from the solar irradiance and getting to the ac output, are implemented [17], [18].…”
