“…Conectarea centralei la SEN este permanentă și nu poate fi întreruptă decât în caz de avarii (nu se acceptă manevre decât în condiții speciale). În plus, conform reglementărilor în vigoare [24][25][26][27][28][29][30], toate centralele racordate la SEN care au o putere de peste 5 MW reclamă dispecerizare permanentă.…”

Deși simplă, această soluție, a determinat în timp apariția fenomenului degradarea proprietăților panourilor solare (alimentate de invertoare)-"înnegrirea panourilor" [20][21][22][23][24][25]. Acest efect (engl., PID -Potential Induced Degradation) se manifestă în final prin reducerea puterii generate de centrală și determină costuri suplimentare importante, impuse de înlocuirea panourilor degradate.…”

The paper presents a study on the quality and energy efficiency of operation for a photovoltaic plant with a power of 8 MW connected to the national energy network. The various operating regimes of the main network elements within the investigated photovoltaic plant are examined both qualitatively and quantitatively. Thus, for power transformers and medium voltage cables in the plant, the losses due to the particular regimes imposed by the load are calculated (often deforming and unbalanced regimes). In this way, opportunities are identified to increase the energy efficiency of the entire system, but also methods to improve the quality of energy delivered at the point of its connection to the local energy system.

“…Otherwise, in normal (daylight) operating mode of the solar park, they became very hot due to high current that cross their windings. In addition to the capacitive reactiv power compensation, it is also proposed to regenerate the properties of the damaged panels (due to their power supply by the inverters that provided compensation during the night) [23][24][25][26][27][28][29]. Thus, when the inverters are disconnected from the circuit the solar panels are powered by special converters called float controller or PID Killer.…”

The paper presents an applicative study on the power quality and energy efficiency operation for a photovoltaic power station with an installed capacity of 8.5 MW. The various operating regimes of the main network elements within the investigated photovoltaic plant are qualitatively and quantitatively. The reactive power flow in the plant that is permanently connected to the grid is especially examined. Thus, the losses within the power transformers and medium voltage cables in the plant are calculated due to the imposed by the load (often deforming and unbalanced regimes). In this manner, opportunities are identified to increase the energy efficiency of the entire system but also methods to improve the quality of energy delivered at the point of its connection to the local energy system.

“…A PI-based P&O algorithm was developed to maintain the output reference voltage of the converter and tracking the MPP of the PV array with reduced power oscillations [14]. A P&O-based voltage regulation loop is designed with a PID controller to increase the tracking speed of the MPP and regulate the output reference voltage faster than the conventional P&O algorithm [15]. A PI-based INC-MPPT algorithm was designed to remove the dilemma of choosing the step size of the converter duty cycle under abruptly changing solar irradiance and temperature [16].…”

Improved Proportional-Integral Coordinated MPPT Controller with Fast Tracking Speed for Grid-Tied PV Systems under Partially Shaded Conditions

When a photovoltaic (PV) system is exposed to physical objects and cloud coverage and connected to bypass diodes, a partial shading condition (PSC) occurs, which causes a global maximum power point (GMPP) and numerous local maximum power points (LMPPs) on the power-voltage (P-V) curve. Unlike conventional MPPT techniques that search for multiple LMPPs on the P-V curve, it is possible to track GMPP straightaway by designing a simple but robust MPPT technique that results in faster tracking speed and low power oscillations. Hence, in this study, an improved proportional-integral (PI) coordinated Maximum Power Point Tracking (MPPT) algorithm is designed to enhance the conversion efficiency of a PV system under PSC with fast-tracking speed and reduced power oscillations. Here, PI controllers are used to mitigating the steady-state errors of output voltage and current of PV system that later on passed through an incremental conductance (INC) algorithm to regulate the duty cycle of a dc–dc boost converter in order to ensure fast MPPT process. The PV system is integrated with the grid through an H-bridge inverter, which is controlled by a synchronous reference frame (SRF) controller. Tracking speed and steady-state oscillations of the proposed MPPT are evaluated in the MATLAB/Simulink environment and validated via a laboratory experimental setup using Agilent solar simulator and dSPACE (DS1104) controller. Results show that the proposed MPPT technique reduces the power fluctuations of PV array significantly and the tracking speed of the proposed method is 13% and 11% faster than the conventional INC and perturb and observe (P&O) methods respectively under PSCs.
