Adjustment of the fuzzy logic controller parameters of the energy management strategy of a grid-tied domestic electro-thermal microgrid using the Cuckoo search algorithm
During the last century, population growth, together with economic development, has considerably increased the energy demand and, although renewable energies are becoming an alternative, still total energy supply is mainly ... -
Analysis of a CIS based PV generator versus a multicrystalline generator under outdoor long-term exposure
The worldwide growth of the PV market has been almost exponential during the last years. Together with conventional crystalline (c-Si) PV modules, “new” commercially available PV technologies such as copper indium ... -
DC capacitance reduction in photovoltaic inverters based on PV voltage feed-forward compensation
In the case of photovoltaic (PV) inverters, an adequate input voltage regulation is fundamental to maximize or limit the power. When employing the traditional control, the input capacitance requires to be oversized in order ... -
DC capacitance reduction in three-phase photovoltaic inverters by using virtual impedance emulation
DC voltage regulation in grid-connected three-phase PV inverters is a fundamental requirement. In order to reduce the influence of the PV non-linear behavior and ensure stability in the whole operating range, the input ... -
Economic analysis of residential PV self-consumption systems with Li-ion batteries under different billing scenarios
In this paper, an economic analysis for four houses with a PV self-consumption system with and without Li-ion batteries is carried out. In particular three different ways of sizing PV and batteries are analyzed under three ... -
Effect of the inner current loop on the voltage regulation for three-phase photovoltaic inverters
In three-phase grid-connected PV inverters, regulating the input voltage is a fundamental requirement. In order to reduce the influence of the PV non-linear behavior and ensure stability in the whole operating range, the ... -
Fuzzy-based energy management of a residential electro-thermal microgrid based on power forecasting
In this paper, an energy management strategy based on microgrid power forecasting is applied to a residential grid-connected electro-thermal microgrid with the aim of smoothing the power profile exchanged with the grid. ... -
Inverter-based PV ramp-rate limitation strategies: minimizing energy losses
This work analyzes the reduction of power generation in strategies that regulate the PV ramp-rate by using inverter limitation. Although the operating principle implies some energy production losses, not all these ... -
Modeling the inherent damping of high-power inverters
In order to decide whether passive or active damping is required in a three-phase inverter, a previous step is to assess the intrinsic damping of the system. However, few works focus on modeling this damping for DC/AC ... -
On the on-site measurement of the degradation rate of crystalline silicon PV modules at plant level
This paper proposes a method for measuring the degradation rate of crystalline silicon PV modules at plant level in two different ways as a form of verification. As actual levels of degradation rate have been observed to ... -
Outdoor performance of a CdTe based PV generator during 5 years of operation
Together with the huge growth of the traditional crystalline silicon (Si-x) PV manufacturers, other thin-film solar cells have also emerged such as cadmium telluride (CdTe) manufacturers. They are characterized by the ... -
Ramp-rate control in large PV plants: battery vs. short-term forecast
The changeability in the power produced by utility-scale PV plants caused by shadows due to passing clouds can compromise grid stability. Traditionally, some kind of energy storage systems (ESS) is proposed as the solution ...
