AN ACTIVE POWER CURTAILMENT MANAGEMENT SYSTEM

NºPublicación: EP3675308A1 01/07/2020

Solicitante:

VITO NV [BE]

Resumen de: EP3675308A1

The present invention is related to the problem of Active Power Curtailment (APC) in single/multiple-phase photovoltaic (PV) systems. During the APC, the inverter in a grid-connected single/multiple-phase PV system fails to inject active power into the low voltage distribution network due to the violation of network voltage upper limit (e.g. 1.10 per unit in Belgium), which leads to a loss of PV power. Therefore, the main focus of the present invention is to minimize this PV power loss to zero by providing a solution/system in order to prevent or reduce APC of such single-phase PV systems.

Resumen de: PL428199A1

Moduł fotowoltaiczny "BOX PV", zwłaszcza jako kompaktowy przestrzenny fotowoltaiczny moduł energetyczny produkujący energię elektryczną ze słońca przedstawiony na rysunku. Istotną wyróżniającą cechą nowego produktu jest stworzenie modułu fotowoltaicznego w sposób umożliwiający pozyskania znacznej efektywności w stosunku do klasycznej, płaskiej konstrukcji panelu PV, szczególnie w sytuacji gdy wymagana jest większa sprawność rozumiana jako wydajność energetyczna przy zajmowaniu mniejszej powierzchni posadowienia. Istota pomysłu zakłada, że zamiast poziomego ustawiania poszczególnych pojedynczych standardowych ogniw fotowoltaicznych zostaną one ustawione w pionie i w szeregu, a energia słoneczna doprowadzana będzie do nich nie bezpośrednio do powierzchni tak jak w klasycznym Panelu fotowoltaicznym, lecz poprzez albo przy udziale materiału fotoaktywnego. Dotychczas uzyskiwana energia z określonej powierzchni płaskiego panelu fotowoltaicznego może zostać pozyskana z urządzenia typu BOX PV, które zajmuje ok. 20 - 30% dotychczasowej powierzchni ale posiada taką samą ilość ogniw.
