Application of Phase Change Materials for Peak Load Shifting Through Price-Based Control Method
… with a price-based control method for peak load-shifting application. A pricebased control method was proposed which would be able to use online real-time electricity price data to use electricity when it is cheap and to stop using it during high peak periods. The proposed method was first …

Stochastic dynamic optimization of consumption and the induced price elasticity of demand in smart grids
… is first presented, which incorporates both load-shifting and storage, and then, the model is decoupled into two subproblems, one for load-shifting and the other for storage. The study of optimal utilization of storage, which is performed analytically and in the presence of ramp constraints, …

Impact of emerging water scenarios on performance of urban water networks
… scenarios: 1) base, 2) conservation, and 3) load-shifting, hydraulic simulations were conducted. Four metrics of network performance are suggested to evaluate responses to scenarios: water loss, water age, energy loss, and peak flow. The results revealed network performance for energy and …

Removing Barriers for Effective Deployment of Intermittent Renewable Generation
… proposed to meet the feeder-scale controllable load with a hybrid renewable generation (including wind and PV) and energy storage system. For the first method, an optimization problem is developed whose objective function is the cost of the hybrid system including the cost of renewable …

Status of grid scale energy storage and strategies for accelerating cost effective deployment
… It was found that the economics of wholesale load shifting are unattractive for any of the emerging energy storage technologies, but that all of the other higher value implementations considered could be reasonably expected to at least break even financially given proper circumstances and the …

Reduction of household energy consumption with innovative energy storage in building structure
… grid benefit of thermal energy storage is load shifting and shedding, which is accomplished by recharging the storage system during off-peak times and substituting heating, ventilation, and air conditioning operation during peak times. Shifting HVAC system operations to times when the …

Day-Ahead Solar Resource Prediction Method Using Weather Forecasts for Peak Shaving
… strategic use of energy storage. In the case of load shifting, energy storage can be used to supply solar energy during a time of day when utility customer's demand is highest, thus providing partial peak load burden relief or peak shaving. Because solar resource availability is intermittent due …

Electric Distribution Reliability Analysis Considering Time-varying Load, Weather Conditions and Reconfiguration with Distributed Generation
… this research takes into account time-varying load patterns, and seeks approaches that are financially justified. An exhaustive search scheme is used to calculate optimal locations for Distributed Generators (DG) from the reliability point of view. A Discrete Ascent Optimal Programming (DAOP) …

Variation Management Strategies for Future Construction Sites: A study to address role of an equipment rental business in the energy transition
… at a construction site for peak shaving and load shifting was evaluated. This was done by optimizing the system cost at the case to see if it is efficient to invest in a battery and be flexible with the load, or purchase electricity directly from the grid. The interviews were a part of …

The value of power grid flexibility : applied optimization methods for bulk electricity storage and technology RD&D
… Electricity storage becomes more valuable as net load variability increases. The impact of net load variability is tested by changing the level of renewable generation resources in the system. The current capital cost of storage-here, compressed air energy storage (CAES)-generally exceeds the …

A Variation of Positioning Phase Change Materials (PCMs) Within Building Enclosures and Their Utilization Toward Thermal Performance
Recently, buildings have been receiving more serious attention to help reduce global energy consumption. At the same time, thermal comfort has become an increasing concern for building occupants. Phase Change Materials (PCMs), which are capable of storing and releasing significant amounts of energy …
