Gravitational Potential Energy

An energy storage car driven by gravitational potential energy was designed. The car could avoid the fixed obstacles set on the track when running. It only uses the gravitational potential energy as power source and doesn’t need to use any other forms of power source. The overall design of the car was completed from some aspects of the steering system, energy storage system and transmission system etc. The cam mechanism is to realize steering of the car. Vortex coil spring is to realize the energy storage in the process of weight falling. Transmission system of the car is composed of fixed pulleys, gear mechanisms and the ratchet mechanisms. Experimental result shows that design of the car is reasonable. The design of the car provides guidance significance for the carbon-free car.

This paper presents the experimental result of a small scale packed bed of random spheres with encapsulated PCM being charged and discharged. A vapor compression refrigerator and heated room with fan heater were used to supply constant heat transfer fluid at a minimum temperature of -28°C for charging and 16°C for discharging. Even though the temperature differences were not fixed in the experiments, the performance of the thermal energy storage is depicted in the form of effectiveness values. Different results were obtained for charging and discharging the thermal storage unit. The differences are expected to come from natural convection and super cooling. The super cooling during the charging process was as high as 6°C.

With the increasing participation of wind generation in the power system, a wind power plant (WPP) with an energy storage system (ESS) has become one of the options available for a black-start power source. In this article, a method for the energy storage configuration used for black-start is proposed. First, the energy storage capacity for starting a single turbine was determined. Then, a hierarchical planning model was established. This model did not consider the starting efficiency of the WPP, but it did consider the layout of the energy storage in the WPP and the balance of the terminal voltage when starting the WPP. Finally, the feasibility and value of the proposed method and model were verified in a 49.5 MW WPP with an ESS (a power rating of 2.24 MW and energy capacity of about 1.68 MWh). The result suggests that configuring an ESS with a small capacity on the side of the turbine can achieve black-start for a WPP with an ESS as the power source.

The Universe

The collapse of a massive star releases a considerable amount of gravitational potential energy. This energy is believed to be the power source of some of the largest explosions in the universe: supernovae, hypernovae, gamma-ray bursts. In this proceedings, we review the mechanisms by which the potential energy from stellar collapse can be tapped to produce these strong explosions, emphasizing how our understanding of massive stars can help constrain these mechanisms.

Power Storage

Elevator energy storage systems provide reliable energy storage using the gravitational potential energy of elevators. The chapter provides evidence that harnessing the gravity of existing infrastructure is economically, environmentally, and socially more responsible than its competitors (large scale hydraulic and lithium battery storage). EESS proposes a heterodox approach to individuals' relationships with power systems. By the use of existing capital to provide power storage, the capitalist cycle, which constructs new capital for the sake of monetary growth, is disrupted. The next generation of energy storage will look to re-constrain its parameters of acceptability on the grounds of environmental and social impact rather than efficiency and megawatt output.

Farm Operators

Transmission system operators impose several grid-code constraints on large-scale wind farms to ensure power system stability. These constraints may reduce the net profit of the wind farm operators due to their inability to sell all the power. The violation of these constraints also results in an imposition of penalties on the wind farm operators. Therefore, an operation strategy is developed in this study for optimizing the operation of wind farms using an energy storage system. This facilitates wind farms in fulfilling all the grid-code constraints imposed by the transmission system operators. Specifically, the limited power constraint and the reserve power constraint are considered in this study. In addition, an optimization algorithm is developed for optimal sizing of the energy storage system, which reduces the total operation and investment costs of wind farms. All parameters affecting the size of the energy storage systems are also analyzed in detail. This analysis allows the wind farm operators to find out the optimal size of the energy storage systems considering grid-code constraints and the local information of wind farms.
