Abstract: In order to fully play the role of battery energy storage (BES) in primary frequency regulation, this paper proposes a self-adaptive control strategy of BES for power grid primary frequency regulation. Firstly, an equivalent model of BES participation in grid primary frequency regulation is established, followed by analyzing the characteristics of virtual droop control and
These battery banks are known as the Battery Energy Storage Systems (BESS). BESS are also considered a better choice for providing a fast response to the power imbalance in the modern power grid by supporting the system frequency regulations (Meng et al., 2020).

The primary law regulating energy sector in Sierra Leone is the National Electricity Act 2011 (“Electricity Act”). This Act incorporates EGTC and establishes EDSA, both of which started operations in 2015. It also sets the legal provisions under which those entities are governed, managed, functioning and are funded.
The purpose of this study is to provide practical guidance and recommendations to the Government of Sierra Leone (GoSL) for the sustainable development of the country's mini-grid sector by building upon lessons learned from the ongoing Rural Renewable Energy Project (RREP) as well as from mini-grid sector development in Nigeria.
In Sierra Leone, where most of the population lives in rural areas and engages in subsistence agriculture, mini-grids can power rural agricultural productivity and create new businesses or expand existing ones linked to the agricultural value chain. (Figure ES-1).
This is one of the key documents on the overall national development strategy of Sierra Leone, including, among other areas – the energy and solar generation sector. It is a recent document, indicating the actual strategic direction of the Government with clear targets and policy actions.
Ministry of Finance The Government of Sierra Leone (GoSL) recognises that the country is endowed with a significant solar energy resource. This potential however remains largely untapped.
