![]() In such times, a PPS can be a lifesaver, as it can run most of your home equipment for a long time. As we all know, the first things to go out when a storm hits your neighborhood is the electrical supply. In addition to their ability to provide user-end on-demand energy, these systems can also play a pivotal role in times of natural disasters. Can be paralleled to provide for on-demand larger storage capabilities.Can get charged from multiple sources (in some cases simultaneously), such as the grid AC supply or via direct DC inputs like solar PV or in-vehicle 12V supplies.Provide both AC and DC forms of power and sometimes at multiple voltages.The PPS, however, also come with special capabilities which differentiate them from simpler equipment, such as portable power banks. The PPS comes in various shapes and sizes, from the small ones giving about 50Wh of energy to larger stations of up to 4kWh capacity, which provides on-demand energy at customer establishments to run various appliances for a significant time.īeing an energy storage equipment, it obviously comes with the relevant battery storage and battery management systems. Portable power stations (PPS) are a new breed of products that allow significant energy storage at the user end and also allow for its use in either AC or DC form. Hence, looking at various aspects, decentralised energy storage systems become very important. More so because the eventual personal usage of energy is mostly done in the DC form. There are inefficiencies in the conversion from AC (sources) to DC (storage) and back to AC for transmission, which compound to make this a bad choice. Apart from operational challenges in large scale energy storage, one of the important factors is that most storage mechanisms use the direct current (DC) form, whereas the production of power and its transmission is mostly in the alternating current (AC) form. 2: Change in energy use vs GDP per capita for India (Source: )īut large scale energy storage is not so sustainable. In fact, power production is usually kept in sync with the ongoing power demand on the grid. However, this produced power needs to be transmitted immediately to loads scattered across the grid. Over the years, it has been found that large-scale power production is sustainable in the long run. To be able to use electrical energy, its stable availability is imperative. So, a postulation as a corollary to the above data is that increasing the per capita energy use can result in increasing per capita GDP of the country!Įnergy usage is distributed across different sources and one of the important forms of energy is electrical energy. ![]() This suggests that the economic development of a developing country corresponds to its per capita energy usage. 1: Energy use per person vs GDP per capita for India (Source: )Īlso, interestingly, not only the actual values but the changes in these two quantities are also strongly correlated, as shown in Fig. 1, it is clear that there has been a strong correlation between these two quantities. Based on the freely available ample data that we have now, as shown in Fig. Another interesting data that can be considered is their per capita energy usage. The difference between developed and emerging economies is generally expressed in terms of their per capita purchasing power parity or the per capita GDP. The PPS come in various shapes and sizes, from the small ones giving about 50Wh of energy to larger stations of up to 4kWh capacity ![]() ![]() ![]()
