Compared with the existing research of energy storage for RE built environment, the advantages and highlights of our study are mentioned as follows: 1. Most studies focus on single energy storage for RES i.e. wither PHS or battery only, however, this paper presents the operation model of hybrid storage. 2.
The onboard low-voltage energy storage power supply scheme uses the original 110 V battery of the train to supply power directly to the traction motor or after boosting voltage. The direct power supply scheme is simple in structure and does not need to reform the train, but the output voltage of the battery is low, only suitable for low-speed

As an aggregator involved in various renewable energy sources, energy storage systems, and loads, a virtual power plant (VPP) plays a key role as a prosumer. A VPP may enable itself to supply energy and ancillary services to the utility grid. This paper proposes a
Diesel generators are commonly used for additional power supply at construction sites today. As a low carbon alternative, Battery Energy Storage System (BESS) has been
With the rapid increase in new energy penetration, the uncertainty of the power system increases sharply. We can smooth out fluctuations and promote the more grid-friendly integration of new energy by combining it with energy storage. This paper proposes an evaluation method for assessing the value of a combined power plant
The uncertainties in the wind power production, thermal power, hydro power, demand, and energy storage are considered in the stochastic model. This study utilises a mathematical programming problem with equilibrium constraints (MPEC) and Karush–Kuhn–Tucker (KKT) conditions to transform the bi-level problem into an
