Abstract

Inihaharap ng propusisyong ito ang isang inobatibong integradong solusyon sa enerhiya na malalim na pinagsasama ang paggawa ng enerhiya mula sa hangin, solar, pump hydro storage, at teknolohiya ng desalinasyon ng tubig dagat. Layunin nito na sistemang tugunan ang mga pangunahing hamon na hinaharap ng mga malayong isla, kabilang ang mahirap na saklaw ng grid, mataas na gastos ng paggawa ng enerhiya mula sa diesel, limitasyon ng tradisyonal na pananakop ng baterya, at kakulangan ng sariwang tubig. Ang solusyon ay nagpapahiwatig ng pakikipag-ugnayan at self-sufficiency sa "power supply - energy storage - water supply," nagbibigay ng maasahan, ekonomiko, at berdeng teknikal na paraan para sa sustainable development ng mga isla.

I. Technical Field and Background Challenges

1. Technical Field

Ang solusyon na ito ay isang interdisiplinaryo, komprehensibong teknolohiya, pangunahing naglalaman ng:

• Paggawa ng Renewable Energy: Paggawa ng enerhiya mula sa hangin at solar photovoltaic power generation.
• Malaking Physical Energy Storage: Pumped hydro storage technology.
• Komprehensibong Paggamit ng Tubig: Reverse osmosis seawater desalination technology.
• Epektibong Intelligent Control: Multi-energy cooperative control at energy management.
1. Background Challenges
• Energy Supply Dilemma: Ang mga malayong isla ay malayo sa mainland grids at karaniwang umaasa sa mataas na gastos na diesel generators. Dahil sa internasyonal na presyo ng langis at kahirapan sa transportasyon ng fuel, ito ay nagreresulta sa mataas na presyo ng kuryente at hindi matatag na suplay, na lubhang nakakapag-limita sa lokal na ekonomikong pag-unlad at kalidad ng pamumuhay ng mga residente.
• Limitations of Traditional Storage: Ang mga tradisyonal na wind-solar complementary systems ay umaasa lamang sa battery storage, na may apat na pangunahing botelya: maikling buhay (nangangailangan ng madalas na pagsasara), mataas na gastos, potensyal na panganib sa kapaligiran, at limitadong capacity. Ang mga limitasyon na ito ay nagpapahirap suportahan ang malaking scale, matagal na stable na energy demands ng mga isla.
• Resource Demand Contradiction: Ang mga isla ay nasa kakulangan ng sariwang tubig. Ang araw-araw na suplay ng tubig ay umaasa sa external transportation o maliliit, mataas na konsumo ng enerhiyang desalination units, parehong napaka-mahal. Ang umiiral na power generation systems at freshwater production facilities ay gumagana nang hiwalay, hindi makakamit ang synergistic use ng enerhiya at resources.

II. Core Technical Solution and System Composition

Ang sistema ay binubuo ng tatlong core modules, organically coordinated through an intelligent controller.

III. System Operating Principles (Three Core Processes)

1. Intelligent Power Distribution and Control Logic (Controller-Led)

The system core is the intelligent controller, which continuously compares "total wind-solar power generation" with "total load demand (resident consumption + desalination unit consumption)":

• Scenario 1: Generation ≥ Load Demand
• Priority is given to charging the small-capacity batteries to replenish their charge.
• Once batteries are full, the pumped storage unit is automatically activated in pumping mode, converting surplus electricity into potential energy.
• If excess power remains, the seawater desalination unit is prioritized to operate at full capacity, converting electricity into valuable freshwater resources.
• Scenario 2: Generation < Load Demand
• The pumped storage unit is automatically activated in turbine mode for hydroelectric generation.
• Simultaneously, the batteries discharge to handle instantaneous peak loads, working together to cover the generation shortfall and ensure continuous power supply.
1. Pumped Hydro Storage Operation Process
• Energy Storage Phase (Low Load / High Renewable Generation): Utilizes low-cost or zero-cost surplus wind/solar power to pump seawater from the lower reservoir (e.g., sea level) to the elevated upper reservoir. This achieves large-scale, long-duration, lossless energy storage.
• Energy Release Phase (Peak Load / No Wind or Sun): Utilizes the height difference to release water, which flows down to spin the reversible pump-turbine and generate electricity. This process starts quickly and responds rapidly, effectively smoothing the randomness and intermittency of renewable power output.
2. Seawater Desalination Synergistic Process

Seawater is intake d and passed sequentially through a multi-media filter (removing large particles) and a cartridge filter (fine filtration). It is then pressurized by the high-pressure pump and sent to the reverse osmosis membrane modules to produce freshwater, which is stored in the product water tank. This entire process is driven by system electricity. Acting as an interruptible, adjustable, high-quality load, it perfectly realizes the synergistic concept of "producing water with electricity, using water production for implicit storage."

IV. Benefits of the Solution

• Maximized Resource Utilization: Fully exploits the island's abundant wind and solar resources, completely replacing or significantly reducing dependence on imported diesel, lowering energy costs at the source, and achieving energy self-sufficiency.
• Revolutionary Optimization of Storage Solution: The hybrid storage model, "Pumped Hydro Storage as primary + Small-Capacity Batteries as auxiliary," fundamentally overcomes the four major drawbacks of traditional batteries. It offers absolute advantages: massive storage capacity, long lifespan (decades), environmental friendliness, and low comprehensive cost.
• Significantly Enhanced System Power Supply Stability and Reliability: Pumped hydro storage can rapidly respond to load changes, providing strong peak shaving and frequency regulation capabilities. Combined with batteries handling instantaneous fluctuations, it gives the island grid stability and power quality comparable to traditional grids.
• Synergistic Satisfaction of Multiple Needs, Killing Multiple Birds with One Stone: Innovatively integrates seawater desalination as a system load, simultaneously solving the two critical survival and development challenges of "lack of electricity" and "lack of water" on islands. It achieves a high degree of integration in "power generation - energy storage - freshwater production," yielding significant comprehensive benefits.
• Prominent Environmental and Green Low-Carbon Advantages: The entire process is based on renewable energy, resulting in zero carbon emissions. It drastically reduces the use and pollution associated with lead-acid batteries. It provides a sustainable green development path for island communities, offering substantial ecological benefits.
