The ancillary services provided by BESS were briefly explained. The short-term ancillary services are known as fast response services that are primarily focused on compensating demand and generation unbalance Mexis and Todeschini (2020).

Is Bess a reliable ancillary solution?

While certain BESS technologies may be reliable and mature IRENA (2015a), with further cost reductions anticipated IRENA (2015b), economic concerns are still preventing BESS from becoming a mainstream solution for ancillary services in power grids Olatomiwa et al. (2016).

Could Bess improve power quality in Indonesia and the Philippines?

BESS could be the most useful in improving power quality in these countries. Indonesia and the Philippines have relatively low electricity access rates, and the potential for microgrids integrated with renewable energy and BESS to achieve 100% electricity access is high.

Can Bess provide multiple grid ancillary services?

BESS has the technical capabilities for providing multiple grid ancillary services Jayasekara et al. (2015); Wang et al. (2018). However, the network providers and market operators may hesitate to deploy the BESS for those services if no regulations, legislation, or guidelines explicitly declare that BESS may do so Bhatnagar et al. (2013).

What are the Bess-based methodologies for long-term ancillary services?

Table 5 presents a summary of the BESS-based methodologies for long-term ancillary services, which are classified as congestion management, peak shaving, and power smoothing. For each journal article, the method, significant contributions, and limitations are summarized and presented in Table 5. TABLE 5. Summary of long term ancillary services.

What are the limitations of the Bess market in Southeast Asia?

Several limitations hinder the development of the BESS market in Southeast Asia. These include the absence of specific regulations and supportive policies, limited technical expertise, high initial costs, fragile grid infrastructure, a rapidly growing yet low share of renewable energy sources, and the availability of low-cost fossil fuels.
