“…In the feedback control configuration, the voltage and current information of the PV system are sent to digital controller and the system is regulated to deliver the maximum output power using a perturb-and-observe control algorithm [14][15][16]. The control structure of the photovoltaic system using digital controller is shown in Fig.…”

-This paper proposes the modeling and control strategy to track the MPPs of hybrid PV and Wind power systems, using a new dual input boost converter. The dual input power conditioning system with an independent MPPT control scheme is introduced with minimum number of circuit elements in order to reduce the switching loss, size and cost of the system. Since the operating conditions for the PV and Wind power systems are very distinct from each other, an efficient and superior control system is required to track the MPPs of both renewable sources with the use of a simply-structured single-ended single-inductor converter. The design of Power-Conditioning System (PCS) and detail control strategy are presented in this paper. To provide independent tracking of MPPs, a variable duty-cycle control strategy is employed for the wind system and a variable frequency strategy is employed for the PV system. Finally, the proposed dual-input converter for hybrid power conditioning system is implemented and the hardware test results are presented. From the hardware experiment, it is concluded that the proposed system successfully tracks the MPPs of both of the renewable power systems independently.

“…In fact, this limiting maximum feed-in power control can be treated as an extension of the active power constraints in the Danish grid code for wind turbine systems. The control concept is also referred to as a constant power generation control [56], [57] or a reduced active power control [58].…”

“…A hybrid control scheme of MPPT and CPG control allows further to increase the penetration level. The CPG control can be implemented by a) integrating energy storage systems like a battery, b) managing the power at the secondary control level, and c) modifying the conventional MPPT algorithms [4], [8], [9].…”

Abstract-Grid operation experiences have revealed the necessity to limit the maximum feed-in power from PV inverter systems under a high penetration scenario in order to avoid voltage and frequency instability issues. A Constant Power Generation (CPG) control method has been proposed at the inverter level. The CPG control strategy is activated only when the DC input power from PV panels exceeds a specific power limit. It enables to limit the maximum feed-in power to the electric grids and also to improve the utilization of PV inverters. As a further study, this paper investigates the reliability performance of the power devices (e.g. IGBTs) used in PV inverters with the CPG control under different feed-in power limits. A long-term mission profile (i.e. solar irradiance and ambient temperature) based stress analysis approach is extended and applied to obtain the yearly electrical and thermal stresses of the power devices, allowing a quantitative prediction of the power device lifetime. A study case on a 3 kW single-phase PV inverter has demonstrated the advantages of the CPG control in terms of improved reliability.
