Impact of compressed air energy storage system into diesel power plant with wind power penetration

Abstract

<p>The wind energy plays an important role in power system because of its renewable, clean and free energy. However, the penetration of wind power (WP) into the power grid system (PGS) requires an efficient energy storage systems (ESS). compressed air energy storage (CAES) system is one of the most ESS technologies which can alleviate the intermittent nature of the renewable energy sources (RES). Nyala city power plant in Sudan has been chosen as a case study because the power supply by the existing power plant is expensive due to high costs for fuel transport and the reliability of power supply is low due to uncertain fuel provision. This paper presents a formulation of security-constrained unit commitment (SCUC) of diesel power plant (DPP) with the integration of CAES and PW. The optimization problem is modeled and coded in MATLAB which solved with solver GORUBI 8.0. The results show that the proposed model is suitable for integration of renewable energy sources (RES) into PGS with ESS and helpful in power system operation management.</p>

Electrochemical batteries for smart grid applications

“…The advantages of these batteries include: they can be made in different sizes and shapes to meet various needs, no memory effect, low self-discharge rate, lighter weight in comparison to other equivalent secondary cells, and it is relatively safe for the environment, and helps to reduce carbon emissions from vehicles. Whereas, the disadvantages include elevated temperatures and high charge levels hasten capacity loss, possess relatively high internal resistance which also increases with aging, and making this storage method cost-effective and developing all the related technologies has proved a challenge and must be addressed before it can be widely accepted [22].…”

Using Y-source network as a connector between turbine and network in the structure of variable speed wind turbine

“…Another advantage of using renewable energy sources is minimizing the size of power production units and increasing the distributed generation units, the proximity of the units of production and consumption of electric power and thus reduce losses and increase efficiency [1]- [22]. One of the highly used renewable energy that had been in consideration is wind energy [1], [4], [14], [16], [19], [20], [23], [24]. Using wind energy specially in windy areas in addition to the economic saving, increased quality will also be delivered.…”
