[Abstract]:The energy management of interconnected power grid is an important research topic in the construction of energy internet. In order to reflect the operational risk level of power system, an improved risk node pricing model (risk-based LMP,RLMP) is proposed by introducing a simplified risk price into the traditional node price (locational marginal price,LMP). Based on the property of production and dissipation of regional system under the bilateral transaction mechanism of power market, a decentralized cooperative risk dispatching framework for interconnected power system without the participation of superior dispatching center is designed. Each regional dispatching center carries out decentralized autonomous dispatching to ensure the economic operation of the regional power grid under the constraint of the specified risk level. In order to maximize the economic benefit of interconnected power system, the adjacent regional dispatching center adjusts the transmission power of tie-line through cooperative mechanism. Finally, a simulation example verifies the effectiveness of the proposed RLMP model and decentralized collaborative algorithm. The results show that the above method can enhance the flexibility of dispatching and control the operational risk of interconnected power systems.
