“…Indonesia is believed to have an excellent potential for developing this type of storage. Indonesia is estimated to have 26,000 potential sites for PHES with a capacity of storage 821,000 GWh in its mountainous areas (Cheng et al, 2019). A detailed map for the finding by Cheng et al ( 2019) of all prospective reservoirs for PHES sites can be seen in Figure 5, while the visualization of potential offriver reservoir pairs can be seen in Figure 6.…”

Indonesia intends to increase the renewable energy ratio to at least 23% from the energy mix generated by 2025. This target is also in line with the Paris Agreement that Indonesia ratified in October 2016. However, renewable energy capacity has not been significant, as 11.38% of the total on-grid power capacity (MEMR, 2021). More than 90% of renewable comes from hydropower and geothermal, and only a limited capacity comes from wind and solar energy. On the other hand, wind and solar energy potential are enormous for energy generation in Indonesia. One of the barriers that hinder the use of both is their intermittent nature so that they are not economically profitable and can disrupt the existing power grid. Energy storage systems (ESS) can reduce this intermittent problem as frequency regulators and voltage support to the grid. This paper reviews the potential and challenges of energy storage and renewable power generation, especially wind and solar power. This paper also outlines lessons learned from energy storage systems that have been implemented and are still under development. The discussion focuses on the types of energy storage suitable for applications in Indonesia.

“…Equatorial countries have reasonable year‐round solar conditions, although the solar resource of Indonesia is lower than in countries in the Mekong region, which contributes to generation costs being higher (Lee et al ., 2019). In addition to domestic opportunities, Asian countries have opportunities to capitalize on offshore and international sites for renewables generation by investing in HVDC cable connections (Cheng et al ., 2019).…”

Asia is facing serious environmental challenges including urban air pollution and the effects of global climate change. As a major source of greenhouse gases, what happens in Asia will play a crucial role in determining the extent to which the world warms over coming decades. This paper reviews key environmental challenges faced by the region and the growing opportunities for a transition to a cleaner economy powered by zero‐emission energy sources. Economic mechanisms – including emissions pricing, reverse auctions, and renewable portfolio standards with green certificate schemes – have the potential to underpin a much greener development model for the Asian Century.

“…Theorem 2 Wind speed (v t ) during the time period t follows Weibull probability density function with shape factor (δ t ) scale factor (τ t ), and v t + 1 will not be impacted by v t , then the expected output fluctuations of a wind-hydro system could be described as Equation (15).…”

Summary This research is motivated by the practice of a well‐known basin—the Yalong River Basin located in the eastern part of the Qinghai‐Tibet Plateau in China, which requires a more reasonable day‐ahead scheduling and operation of a wind‐pumped‐hydro system. Optimal electricity flow remains a widely‐cultivated topic within power system research community since its inception about half‐a‐century ago. In contrast to previous studies, this article proposes a multiobjective multistage nonlinear model to not only for the technical pump‐operating constraints of the coordinated system, but also for lessening the variations on the active power output coming from the intermittence variability of the wind energy resource. Specifically, minimizing the fluctuations of the power output and minimizing the “abandoned rate” of the wind and hydro power are considered two objectives. A state transition equation to compute the energy balance in the reservoir is introduced in the constraint for scheduling the pump‐hydro system. Moreover, the expected operator and chance constraint are used to deal with the stochastic wind energy output. Finally, the scheduling of a wind‐pumped‐hydro system of the Yalong River Basin is proposed as a practical example to illustrate the effectiveness, feasibility, and validity of the proposed model.
