Is the electric grid duck curve bad? 


Best insight from top research papers

The electric grid duck curve is considered problematic due to the challenges posed by the rapid integration of solar energy into the grid. The duck curve phenomenon occurs when there is an excess of solar generation during peak hours and a shortfall during off-peak periods, leading to operational difficulties. Various strategies have been proposed to mitigate the duck curve effects, such as utilizing pre-cooling techniques in residential households , implementing deep reinforcement learning-based strategies for demand response and dynamic pricing , and employing methodologies involving open-source platforms for optimization . These approaches aim to flatten the net demand curve, improve system stability, and enhance grid efficiency in the face of increasing solar PV penetration.

How do renewable energy sources impact the grid?5 answersRenewable energy sources (RESs) have a significant impact on the power grid. As traditional synchronous generators are being replaced by inverter-based RESs, the grid's inertia is gradually decreasing, which can pose challenges to grid frequency stability. The integration of RESs has caused blackouts in power systems worldwide due to the lack of grid support functions in early RES technologies. The characteristics of the electrical grid, such as the inertia constant and the rate of change of frequency, need to be evaluated for power systems dominated by RESs. The safe disconnection of distributed energy resources (DERs) from the grid becomes crucial during power outages to maintain frequency stability. Increasing DER integration decreases the allowable limit of DER disconnection to prevent blackouts, and there is a negative linear correlation between the maximum allowable disconnection level of DER and the level of DER penetration.

What is the impact of online customer reviews in services?
10 answers
Online customer reviews significantly influence the service industry, affecting both consumer behavior and business strategies. The presence of online reviews has been shown to encourage firms to adapt their quality and pricing strategies to meet customer expectations, with a tendency to increase quality and lower prices initially, followed by a later stage of decreased quality and increased prices as firms respond to the evolving landscape of customer feedback. This dynamic underscores the importance of managing online customer perceptions through quality and pricing adjustments. Moreover, user-generated content (UGC) on social media plays a crucial role in shaping customer choices and enhancing service providers' brand equity, revenue, and service innovations, particularly in the hospitality and tourism sectors. The analysis of big data from online reviews reveals that service, room, and value evaluations are critical components influencing customer satisfaction, while negative emotions and brand type can adversely affect guest satisfaction. Online reviews also foster product innovation, especially in software, where both the sentiment and quantity of reviews positively impact iterative innovation. However, the complexity of a product can moderate this relationship, indicating that not all feedback is equally useful for all types of products. The perceived risk associated with services can be mitigated by online reviews, leading to more positive behavioral intentions among consumers. The COVID-19 pandemic has further highlighted the role of online reviews in reflecting shifts in consumer perceptions and evaluations of service experiences, with a noticeable increase in the expression of negative emotions. In the hotel industry, understanding customer experiences through online reviews is essential for maintaining satisfaction and fostering repurchase intentions, with service and dining factors significantly affecting customer satisfaction. Similarly, in the educational sector, service quality and electronic word-of-mouth (e-WOM) have been identified as key influencers of customer satisfaction and word-of-mouth intentions, suggesting that service providers should leverage social media channels to exceed customer expectations. The global service industry relies on online reviews for critical information that shapes consumer purchasing decisions and firms' operational strategies. For boutique hotels, addressing service quality gaps identified through online reviews is crucial for maximizing customer satisfaction and supporting the tourism industry.
