“…Hydroelectric power is a form of power change from hydropower with a certain height and flows into electric power, using a water turbine and a generator. Therefore, the power generated is dependent on the high and flowrate of the water [28] [29]. The illustration of a pico hydropower plant is shown in Fig.…”

A hydroelectric power plant is an electrical energy generator that utilizes water energy to drive a water turbine coupled to a generator. The main problem in hydroelectric power plants is the frequency and voltage fluctuations in the generator due to fluctuations in consumer loads. The purpose of this research is to make a prototype of the Electronic Load Controller (ELC) system at the Pico Hydropower Plant. The main part of ELC is the frequency sensor and gating system. The first part is made by a Zero Crossing Detector, which detects the generator frequency. The gating system was developed with TRIAC. The method used is the addition of a complement load which is controlled by delaying the TRIAC. Load control is intended to maintain the stability of the electrical energy produced by the generator. The PID algorithm is used in frequency control. The results of the frequency sensor accuracy test are 99.78%, and the precision is 99.99%. The ELC system can adjust the frequency automatically by setting the firing delay on the TRIAC to distribute unused power by consumer loads to complementary loads so that the load used remains stable. The ELC is tested with increasing and decreasing load. The proposed ELC gives a stable frequency at 50Hz. Whereas at the first test, the mean voltage is 183V, and in the second test is 182.17V.

“…The researcher scrutinized the availability of water sources, flow rate, and head of the river. The water flow rate and head height of Camias River were measured as they influence the design of the hydroelectric power plant [14,15]. The measurement of water flow rate was determined by the average velocity ( ) and average area of the river.…”

By focusing on the practical application of knowledge, this applied research aims to develop a power system as a viable and sustainable solution to address the energy needs of the community that considers factors such as energy demand, available resources, and cost-effectiveness. Camias River is a waterbody in Porac, Pampanga with a nearby rural community that has difficulty affording relatively expensive power supply. The river has a head height of 0.8 m and flow rate of 5.40 m3/s with a stable flow of water all year round, indicating the feasibility of establishing a hydroelectric powerplant. When a weir is installed across the river, the head height becomes 3 m, resulting in greater accumulation of renewable energy through the hydroelectric powerplant. It is calculated that with this feature, the potential power production in total is 24,401 watts. Based on computation, the electricity usage of the identified 78 households in the community is 17,160 watts, with typical load of 220W (2-light bulb 20W and 1-outlet 180W) per household. This required electric capacity can be covered by the proposed 20-kW hydroelectric powerplant. The proposed design has a total computed cost of ₱3,368,888 with an estimated annual net profit of ₱868,201.

This research proposes a new rooftop rainwater energy harvester using electromagnetic generators, which demonstrates better rain-energy harvesting performance than the traditional rainwater energy harvesters that use electromagnetic generators under light rain conditions. Conventionally, the rainwater collected from the roof of a building or a residential attic using the installed roof gutter system is drained directly along a pipe to drive water turbines combined with electromagnetic generators for generating electricity. Such an energy harvesting method has high energy harvesting efficiency under heavy rain conditions but is inefficient under light rain conditions. To improve the energy harvesting efficiency in light rains, a pipe-connected tank including a passive rainwater buffer is introduced and fixed below the rooftop gutters in the proposed structure. The passive rainwater buffer is attached above the pipe-connected tank. After collecting a certain amount of rainwater from the gutters, the passive rainwater buffer automatically releases the rainwater periodically into the pipe-connected tanks. The released rainwater results in a large flow along the pipe, which can drive water turbines with electromagnetic generators to work at a high efficiency for a short period of time. A small-scale experimental prototype was built for validating the energy harvesting performance of the proposed structure. The results show that the intermittent highefficiency power generation of the proposed structure is better than the continuous low-efficiency power generation of the traditional structure during light rains. The proposed structure can charge a 680 μF capacitor with at least nine times the electrical energy that is stored in a conventional capacitor for a rainwater flow rate of less than 300 mL/min in the same amount of time. However, with the increase in the rainwater flow, the energy harvesting performance gap between the proposed structure and the traditional one gradually narrows.
