Optimal operation of virtual power plants with shared energy storage

Optimal operation modes of photovoltaic-battery energy storage system based power plants considering typical scenarios

Recent advances in battery energy storage technologies enable increasing number of photovoltaic-battery energy storage systems (PV-BESS) to be deployed and connected with current power grids. The reliable and efficient utilization of BESS imposes an obvious technical challenge which needs to be urgently addressed. In this paper, the optimal operation of PV-BESS based power plant is investigated...

Optimal Operation System for Energy Plants

Against a backdrop of healthy domestic and foreign demand, the steel industry is continuing its fundamental trend of increasing production for the manufacturing industry. Meanwhile, since the steel industry accounts for approximately 11% of final energy consumption in Japan, efforts to improve the efficiency of energy usage have been pursued actively for a long time. Since the first oil crisis,...

Determining the Optimal Strategy of Multi Virtual Power Plants using GA-GT

abstract: In the present work, determining the optimal strategy(profit based) of multi virtual power plants (VPPs) as well as the objective of maximizing profit through the multi-level control of VPPs are discussed by the micro-grid utilization center including virtual power plants. VPPs include renewable resources such as wind farms, photovoltaic, and conventional resources such as fuel cell, ...

A Model-based Optimal Operation Strategy for Compressed Air Energy Storage (caes) Plants

A model-based optimal operation strategy for an energy storage system exhibiting significant stand-by energy losses is presented. Specifically, a thermodynamic model of an advanced adiabatic compressed air energy storage (AA-CAES) plant, consisting of compression/expansion trains, a thermal energy storage (TES) system, and an underground cavern for compressed air storage, is used in this work. ...
