FAQS

What is Tunisia's energy transition strategy?

With abundant renewables sources, renewable energy technologies constitute the main pillar of Tunisia’s energy transition strategy given the socio-economic benefits that this strategy will provide to the Tunisian economy in terms of increased investments, a clean economic growth, job creation and preserving the environment.

What is the energy system in Tunisia?

In BAU, the Tunisian energy system is based on the continuation of already legislated policies, current trends, existing plans and cost improvements in low-carbon technologies, without considering additional climate targets, with fossil fuels remaining the prime forms of energy until 2050 ( Table 1 ). Table 1.

Who manages the energy sector in Tunisia?

As of March 2020, the Tunisian electricity sector is managed by the Ministry of Energy, Mines and the Energy Transition. For the past two years, renewable energy portfolio was managed by the Ministry of Industry, Small and Medium Size Enterprises.

What is a multi carrier energy system?

Although operation of a multi carrier energy (MCE) system is more complex than the single carrier energy (conventional) systems, but the MCE systems can reach to a stable, resilient, and robust operation because of their access to various energy forms at the same time [ ].

How much power does Tunisia have?

Tunisia’s total installed renewable power generating capacity had reached approximately 352 MW by the end of 2019, with wind energy at 245 MW, hydropower at 66 MW) and PV at 62 MW (IRENA, 2020b).

How many MW is a solar power system in Tunisia?

It is subject to authorisation by MIEM and is set by Decree No. 2016-1123: 10 MW for solar PV and solar thermal; 30 MW for wind energy; 15 MW for biomass; and 5 MW for projects using other renewable resources. Box 3. Addressing power system flexibility in Tunisia

Energy storage power station low frequency oscillation

Since the low-frequency oscillation between two connected power systems is active power oscillation, power modulation through energy storage devices (ESDs) can be an efficient and effective way to maintain such power system stability.

FAQS

Can a battery energy storage system control low-frequency oscillations?

The motivation for the current study is to address low-frequency oscillations by proposing a battery energy storage system (BESS) controller. The BESS is connected to the power system through a DC/AC voltage source converter, which is a common configuration for grid-connected BESS systems.

What causes low-frequency oscillations in electric power systems?

Malkova The development of electric power systems determines the growing probability of low-frequency oscillations, which can be reason of system faults. Traditionally, the task of damping low-frequency oscillations is assigned to synchronous generators, by appropriate setting of the automatic voltage regulator parameters.

Do low-frequency oscillations threaten power system stability?

Low-frequency oscillations (LFOs) are becoming crucial in large interconnected smart grids. They do not threaten power system stability until sufficient positive damping 1. However, Negatively damped LFOs are of concern and should be detected and damped in real time to avoid power system failure 2.

Are battery energy storage systems a power oscillation damping device?

Consequently, ESSs have garnered significant attention for enhancing power system behavior and are considered as power oscillation damping devices in this study. The motivation for the current study is to address low-frequency oscillations by proposing a battery energy storage system (BESS) controller.

How to study low frequency oscillation among power utilities?

Widely used methodology for studying low frequency oscillation among power utilities is also presented. Methods for oscillation damping, both at operational and planning stages of power system are briefly discussed. A comprehensive case study of low frequency oscillation in simple system is presented using eigenvalue analysis.

Does a low-frequency oscillator outperform a PSS?

The results demonstrate that the proposed method outperforms the PSS in terms of damping low-frequency oscillations and enhancing the dynamic stability of power systems across different conditions and operating points.
