Wind Power Curtailment and Energy Storage in Transmission Congestion Management Considering Power Plants Ramp Rates

Abstract

Artículo de publicación ISIThe integration of intermittent generation in power grids, such as wind energy, imposes new challenges for transmission congestion management. In order to solve this problem, energy storage systems (ESS) have been proposed in the literature, as they provide an efficient mechanism for balancing variability while reducing operational costs. This paper presents a comprehensive analysis of the dynamic interactions between wind energy curtailment and an energy storage system (ESS) when the ramping rates of power plants are considered. An analytical framework is developed to study different mitigation measures in terms of total energy curtailed, total congestion costs, line load factor and congestion probability. This framework is tested in a real case study and a sensitivity analysis is performed to identify the influence of the main ESS design parameters in congestion mitigation performance

Robust computational framework for mid‐term techno‐economical assessment of energy storage

“…Due to their limited capacity, their operation will not change market prices. The following constraints are used for defining energy storage charge and discharge behaviour [27]:…”

“…The outcome of (27) gives the DV set. It is interpreted as follows: If the decision maker follows the DV pattern, then he can be hopeful that the objective function is able to reach (to β o % less than f b ) as far as wind uncertainties are at leasť α.…”

Energy Storage Management via Deep Q-Networks

“…Energy storage systems provide an opportunity to increase the grid efficiency and cope with fluctuating renewable energy generators [1]. The ability of batteries to respond quickly to changes in the system makes them ideal candidate for a wide range of power systems applications, including spatio-temporal energy arbitrage [2], peak shaving [3], frequency [4], and congestion management [2], [5].…”

Technical and economic analysis on grid-connected wind farm based on hybrid energy storage system and distributed generators

“…Applications of the ESSs in various subsystems of the power systems are considered and reviewed well in the literature [5,6]. ESSs have been widely applied in generation [7][8][9][10], transmission [11,12], and distribution sectors [13] of the electric power systems. Distribution network as one the structural units of the electric power system also benefits from some achievable applications of the ESSs in this network [13,14].…”
