In present time, most of the power generation utilities in the north of Canada use only diesel generators (DGs) to satisfy their needs for electrical power. Usually, DGs uses oil as a primary source, which is relatively inefficient, very expensive to transport, and responsible for the emission of large amounts of greenhouse gases (GHG). To overcome these drawbacks and ensure uninterruptible power supply with high power quality improvement, as well as, with reduced cost, hybrid standalone power generating system using wind turbine, solar PV array and Hydro is advocated. Usually, most of renewable energy sources suffers with the intermittency in nature. To solve this problem and ensure uninterruptable power supply to the local load, battery energy storage system (BESS) is required. Indeed, lead-acid battery technology is widely used because of its low cost. However, it possesses limitations such as, low energy density and a limited number of charge/discharge cycles. Furthermore, these batteries may damage by a poor charging control results in overcharging. In addition, lead acid battery is typically rated at 77F (25C°). The low and high ambient temperatures also affect the performance, lifespan, as well as recommended charging voltages. To solve these problems related to the lifespan of lead-acid batteries, energy density, and profitability of the system, hybrid storage system (lead-acid batteries and super-capacitors) is advised. Furthermore, advanced control algorithms are required to control the power among various sources. The design of the controller is also required to achieve high efficiency and to extend the lifespan of batteries with the generating system.

目前，加拿大北部的大多数发电设施仅使用柴油发电机（DG）。 以满足他们对电力的需求。通常，DG使用石油作为主要来源，这相对来说 效率低，运输成本高，排放大量温室气体 （温室气体）。为了克服这些缺点，确保高电能质量的不间断电源 本发明涉及改进以及降低成本的使用风力涡轮机的混合独立发电系统， 太阳能光伏阵列和水电是提倡的。通常，大多数可再生能源都受到 在自然界中的不稳定性。为了解决这一问题并确保对本地负载的不间断供电， 电池储能系统（BESS）。事实上，铅酸电池技术被广泛使用，因为 它的低成本。然而，它具有能量密度低和数量有限等局限性 充电/放电循环。此外，这些电池可能由于不良的充电控制而损坏， 收费过高。此外，铅酸电池的额定温度通常为77 F（25 ℃）。低和高环境 温度也影响性能、寿命以及推荐的充电电压。解决这些 与铅酸电池寿命、能量密度和系统盈利能力有关的问题，混合动力 建议使用蓄电池系统（铅酸电池和超级电容器）。此外，先进的控制算法 需要控制各种电源之间的功率。控制器的设计还需要 实现高效率和延长电池的使用寿命。
