The largely government owned electricity sector in Haiti, referred to as Électricité d''Haïti (ED''H for "Haiti Electric Utility", faced a deep crisis characterized by dramatic shortages and the lowest coverage of electricity in the Western Hemisphere in 2006. with only about 38.5% of the population having regular access to electricity. In addition, Haiti''s large share of thermal generation (70%) makes the country especially vulnerable to rising and unstable oil prices.
Power stations fuelled by fossil fuels or nuclear fuels are reliable sources of energy, meaning they can provide power whenever it is needed. However, their start-up times vary according to the
In addition, the energy storage configuration effectiveness of the cooperative alliance is also superior to that of individual energy power stations when equipped with energy storage separately. From an economic perspective, when individually configuring energy storage for wind farms, the main revenue in the objective function
By following above steps, the AHP is used to calculate the score values of different energy storage power stations, and the regulation and control ability of energy storage power stations is evaluated.

A few points to note about this data: Renewable energy here is the sum of hydropower, wind, solar, geothermal, modern biomass and wave and tidal energy. Traditional biomass – the burning of charcoal, crop waste, and other organic matter – is not included. This can be an important energy source in lower-income settings.
With the development of the new situation of traditional energy and environmental protection, the power system is undergoing an unprecedented transformation[1]. A large number of intermittent new energy grid-connected will reduce the flexibility of the current power system production and operation, which may lead to a decline in the utilization of
