An Expert-based Approach for Grid Peak Demand Curtailment using HVAC Thermostat Setpoint Interventions in Commercial Buildings
… explores the idea of inducing grid peak demand curtailment by turning commercial buildings into interactive assets for building owners during the demand control period. The work presented here is useful for both ab initio design of new sites and for existing or retrofitted sites. An analytical …

Overvoltage Prevention in Low Voltage Rural Distribution Network with High Penetration of Wind Energy
… solution to overvoltage problem, active power curtailment is a very attractive solution since only small adjustments in the controllers are necessary for implementing this technique and is activated only when needed. In wind energy systems, this can be achieved by adjusting the pitch angle of …

Assessment of the impacts of demand curtailments in the DAMs: issues in and proposed modifications of FERC Order No. 745
… purchase payments of loads not participating in curtailment provision so that those buyers are worse off due to the DRR demand curtailments presence in the DAMs. The second set of unintended consequences consists of the cases where the participation of DRRs results in higher prices to their …

Power System Resilience Enhancement Using Artificial Intelligence
… of component outages and the resultant load curtailment in response to extreme events is an essential task in pre- and post-event planning, recovery and hardening of power systems. Power system resilience improvement is investigated in this work from component outage prediction to identifying …

A Multiagent Energy Management Control System for Commercial & Industrial Applications
… with their power provider to permit voluntary curtailment of power consumption to be negotiated by a human operator. Even still, at the customer-side there are needs to maximize cost savings and automate decision making, and at the provider-side there are needs to reduce peaking demand and …

Creating markets for wind electricity in China : case studies in energy policy and regulation
… leads the world in renewable energy deployment, curtailment (waste) of wind and solar is high and increasing, generating much discussion on the relative contributions of technical inflexibilities and incomplete institutional reforms on integration outcomes. These integration challenges directly …

Regulatory and technical barriers to wind energy integration in northeast China
… 2.7% of national generation, while the rate of curtailment (available wind not accepted by the grid operator onto the system) reached 12%. Wind integration challenges have arisen in China for technical, economic and institutional reasons. From a technology standpoint, the variability and …

Innovative energy systems and processes based on hydrogen from RES and its derivatives in the energy transition process
… affects grid stability and can lead to energy curtailment. By converting surplus renewable electricity into chemical energy carriers such as hydrogen and ammonia, it is possible to enhance system flexibility, support grid services, and provide carbon-free fuels for hard-to-abate sectors and …

Renewables Integration Challenges of the Energy Transition
… limitation using both economic dispatch and curtailment analysis methodologies. From a network perspective, this inflexibility is particularly significant with respect to wind power from Scotland (both onshore and offshore), resulting in increased rates of curtailment. From a market …

Investigation of factors driving the costs of operating the 2020 Irish power system with large-scale wind generation
… results in terms of total generation costs, wind curtailment and generator technology type dispatch. In particular accounting for these issues has resulted in wind curtailment being predicted in much larger quantities than had been previously reported. This would have a large effect on wind energy …

Effect of pregnancy on adipose tissue biology in a mouse model of obesity
… that pregnancy was associated with an unexpected curtailment of visceral (mesenteric) adipose tissue mass in HF mice and with an attenuation, rather than worsening of the metabolic impairment expected from the combination of excess dietary fat and insulin resistance/glucose intolerance of …

Understanding technology diffusion and market adoption through modeling : implications on strategy for demand-side energy firms
… of demand and diminishing margins for Curtailment Service Providers (CSPs) in the long run. We propose recommendations to surmount these challenges. To tap the smaller commercial and residential markets, CSPs must extend its reach by partnering with composite channel partners, who in …
