As the proportion of behind-the-meter (BTM) renewable energy resources (RERs) in distribution network continues to rise, precise role RERs flexibility market, whether as "Recipients" or "Providers", is becoming less distinct. This observation has led us explore integration flexible load and into markets. Such facilitates resource sharing among multiple microgrids (MGs). paper focuses on potential emergence a secondary (SecFlex) market power sector high proportional BTM-RERs microgrids. Within concept SecFlex this outlines comprehensive process supporting trading, which includes "SecFlex organization–trading volume collation–response schedule optimization". At first, mechanism proposed, where players submit an empirical curve organizer. During clearing stage, social welfare equilibrium problem solved. Subsequently, trading adjusted collation stage account for (DN) voltage magnitude balance. Finally, response strategy designed analyze behaviors players. The cvxpy framework used solve competitive paper. results show significant cost reductions two players, by 77.8% 24.0% respectively. However, costs Player 3 have increased substantially, up 4.6 times baseline when limited. These findings provide theoretical guidance development market.

Concentrated Solar Power (CSP) plants integrated with Thermal Energy Storage (TES) represent a promising renewable energy source for generating heat and power. Binary molten salt mixtures, commonly referred to as Salts, are utilized effective transfer fluids storage media due their thermal stability favorable thermophysical properties. However, these mixtures pose significant challenges high solidification temperatures, around 240 °C, which can compromise the longevity reliability of critical system components such pressure sensors bellows seal globe valves. Thus, it is essential characterize performance, assess under various conditions, understand failure mechanisms, particularly in relation temperature fluctuations affecting fluid’s viscosity. This article discusses experimental tests conducted on sensor valve, both designed direct contact salts CSP environments, at ENEA Casaccia Research Center laboratory Rome. The methodology conducting detailed, guidelines outlined optimize plant operation. findings provide insights improving component design maintenance minimize unplanned downtime. They also offer methodologies installing measurement instruments electrical heating systems components.

With the accelerated transition of global energy structure towards decarbonization, share PV power generation in system continues to rise. IEA predicts will account for 80% new renewable installations during 2025–2030. However, latent faults emerging from long-term operation photovoltaic (PV) plants significantly compromise their operational efficiency. The existing EL detection methods face challenges including grain boundary interference, probe band artifacts, non-uniform luminescence, and complex backgrounds, which elevate risk missing small defects. In this paper, we propose a high-precision defect method based on BiFDRep-YOLOv8n target defects plants, aiming improve accuracy real-time performance provide an efficient solution intelligent plants. Firstly, visual transformer RepViT is constructed as backbone network, dual-path mechanism Token Mixer Channel Mixer, achieve local feature extraction information modeling, combined with structural reparameterization technique, enhance sensitivity detecting Secondly, multi-scale characteristics defects, neck network optimized by introducing bidirectional weighted pyramid (BiFPN), adopts adaptive weight allocation strategy fusion characterization at different scales. Finally, head part uses DyHead-DCNv3, combines triple attention scale, space, task awareness, introduces deformable convolution (DCNv3) modeling capability irregular
