Energy crisis and environmental pollution have drawn lots of attentions to the development of renewable energy. As a clean renewable energy source, photovoltaics (PV) generation has been experiencing a dramatic growth worldwide. Aiming at the accelerate trading of distributed PV in the electricity market, this paper proposes a P2P distributed PV day-ahead market trading mechanism based on continuous matching. In addition, an optimal bidding strategy is developed based on a bidding tendency model to maximize trading benefits. Numerical results show that the transaction architecture and mechanism can promote the consumption of photovoltaic energy among peers, and effectively improve the transaction profit of peers.
