A resilient hybrid energy power system

Supplying power to traditional communication infrastructure becomes more complex and diversified as multiple energy supplying sources are introduced to the infrastructure such as: 1. Diesel Generators 2. Solar & Wind 3. VRLA (Valve Regulated Lead Acid) Batteries 4. Gel & Lithium Iron Phosphate Batteries 5. Variable demand of site electricity requirements e.g. 48V DC, 24V DC, 220V AC This paper introduces types of input energy based on hybrid energy power supply scenarios which are categorized into three categories & 11 scenarios. A kind of hybrid energy power system architecture is also presented which consists of six units. Selecting different units can achieve personalized site equipment portfolio to effectively provide power supply solutions for three categories & 11 scenarios, which could effectively meet diversified power supply requirements and fulfil need of product customization and delivery on large scale. For the new telecom site construction, hybrid energy power systems can be deployed rapidly. To transform existing site, hybrid energy power system can take full use of the existing site power infrastructure (such as diesel generates, converters, batteries etc) to maximize the output of already made investments. Upgrade and evolution of power supply system can be achieved smoothly with this type of power system. For example, from mains-diesel generator hybrid to solar-mains-diesel generator hybrid and wind-solar-mains-diesel generator hybrid, can gradually increase the renewable energy electricity proportion, reduce fuel/oil and mains power supply costs of communication base station and helps to improve operator´s overall operating revenues.
