Bidding Agents for PV and Electric Vehicle-Owning Users in the Electricity P2P Trading Market

As the world strives to decarbonize, the effective use of renewable energy has become an important issue, and P2P power trading is expected to unlock the value of renewable energy and encourage its adoption by enabling power trading based on user needs and user assets. In this study, we constructed a bidding agent that optimizes bids based on electricity demand and generation forecasts, user preferences for renewable energy (renewable energy-oriented or economically oriented), and owned assets in a P2P electricity trading market, and automatically performs electricity trading. The agent algorithm was used to evaluate the differences in trading content between different asset holdings and preferences by performing power sharing in a real scale environment. The demonstration experiments show that: EV-owning and economy-oriented users can trade more favorably in the market with a lower average execution price than non-EV-owning users; forecasting enables economy-enhancing moves to store nighttime electricity in batteries in advance in anticipation of future power generation and market prices; EV-owning and renewable energy-oriented users can trade more favorably in the market with other users. EV-owning and renewable energy-oriented users can achieve higher RE ratios at a cost of about +1 yen/kWh compared to other users. By actually issuing charging and discharging commands to the EV and controlling the charging and discharging, the agent can control the actual use of electricity according to the user’s preferences.

Solar energy and regional coordination as a feasible alternative to large hydropower in Southeast Asia

Strategic dam planning and the deployment of decentralized renewable technologies are two elements of the same problem, yet normally addressed in isolation. Here, we show that an integrated view of the power system capacity expansion problem could have transformative effects for Southeast Asia’s hydropower plans. We demonstrate that Thailand, Laos, and Cambodia have tangible opportunities for meeting projected electricity demand and CO2 emission targets with less hydropower than currently planned—options range from halting the construction of all dams in the Lower Mekong to building 82% of the planned ones. The key enabling strategies for these options to succeed are solar PV and regional coordination, expressed in the form of centralized planning and cross-border power trading. The alternative expansion plans would slightly increase the cumulative costs (up to 2.4%), but substantially limit the fragmentation of additional river reaches, thereby offering more sustainable pathways for the Mekong’s ecosystems and riparian people.

Power Trade in South Asia: Developing A Framework Based on Case Studies of Power Trading Arrangements in Europe and Asia

South Asia is the fastest growing region in the world and is experiencing increasing demand for energy. As a result, countries are witnessing an excessive reliance on fuel imports, making themselves vulnerable to external price volatility and compromising on energy security. Power trade in South Asia can meet the challenge of increasing energy demand owing to complementarities in resource endowments and peak demand. Power trade in South Asia has increased over the years but is below potential. However, there are various challenges due to lack of institutional structures and frameworks for developing regional power trade models. The examples of power integration models in Europe, that is, the Nordic power market, and in Southeast Asia, that is, power trade in the Greater Mekong Subregion (GMS), can provide useful lessons and international best practices for regional power trade to be replicated in the South Asian context. Based on this, the objective of this article is to evaluate the existing power trading mechanisms in South Asia, highlight the challenges to regional energy cooperation, outline the necessary instruments and catalysts to promote regional power trade in South Asia based on the case study of successful power trading arrangements, including the Nordic power market in Europe and the Greater Mekong Subregion (GMS) in Southeast Asia, draw on their experiences to identify key mechanisms and develop a template for greater regional cooperation in electricity in South Asia.

Distributed Power Trading System Based on Blockchain Technology

The power trading system has the characteristics of nonlinearity, dynamics, and complexity. Part of the business data in the trading system needs to be exposed to numerous external business systems. The traditional centralized power trading model has some problems, such as low data security and trust crisis of regulators. Blockchain technology provides prominent ideas for solving these problems. Firstly, the improved AdaBoost algorithm is used to predict the supply and demand gap of power trading nodes. Secondly, based on the fact that the information on the blockchain is only open to the power supply side, a two-stage game model of asymmetric information between the power supply side and the power user is constructed to capture the price competition behavior between them in order to find the Nash equilibrium price in two stages. Finally, the US PJM market electricity market data are used to carry out an example analysis to verify the effectiveness of the algorithm and model.
