The efficient utilization of clean energy resources to meet increasing electricity demand is imposing the integration of the electricity market and the construction of secure transmission mechanisms around the globe Accordingly, the Association of Southeast Asian Nations (ASEAN) is integrating its large geographical power transmission infrastructure via the ASEAN power grid (APG) This study extensively reviews the energy resources (ie, fossil fuels and renewables), the current utilization, and the future projection for ASEAN Electricity export-import scenarios and renewable generation based transmission expansion planning practices in ASEAN will also be critically reviewed in this work Additionally, the major barriers and technical challenges for establishing an ASEAN grid will be briefly analyzed Finally, this work suggests possible techniques that help expedite the renewable power generations to overcome the limitations associated with the establishment of the APG, as well as future research direction in enhancing the utilization of APG for ASEAN

ASEAN power grid: a secure transmission infrastructure for clean and sustainable energy for South-East Asia

For cross-regional transmission projects, the two-part transmission pricing mechanism is suggested so as to promote the sustainable development of cross-regional electricity trading. In the two-part transmission pricing mechanism, appropriately determining the capacity charging ratio (CCR) is an important issue not well solved. Given this background, a Z-number-based risk-minimised negotiation model is developed for a transmission company and a power purchaser to achieve an agreeable CCR under incomplete information. The uncertainty distribution of the future annual electricity transmission quantity is first estimated by the Z-number-based multiple Z-valuations; and then, the benefit and risk loss measured by the well-established conditional value at risk (CVaR) are analysed for the participating two parties. Subsequently, the negotiation model where each negotiator is to minimise its risk loss under a given lowest acceptable benefit constraint and the estimations of the opponent's risk tolerance and negotiation strategy is presented to determine the optimal offer. Finally, the ± 500 kV Xiluodu−Guangdong direct current (DC) transmission project in the southern region of China is employed to demonstrate the basic characteristics of the proposed model.

Fully integrated regional electricity markets would result in large efficiency gains and potentially huge economic savings for all the countries involved. This is true in the short term (lower system operation costs), but also, and more relevantly, in the medium and especially long term (optimal resources exploitation and coordinated capacity expansion). Nevertheless, for regional markets to be successful, new institutional arrangements are necessary to improve trust in the firmness of cross-border contracts and trades, especially during scarcity conditions. This article identifies the main barriers that have hampered cross-border trading in regional markets so far, and discusses alternatives to mitigate their negative impact.
