Grid Operation

To economically dispatch distributed energy resources (DERs) while addressing operational concerns of the electric grid, distribution locational marginal price (DLMP)-based market frameworks have been formulated for the electric distribution grid. This paper proposes to extend this methodology to thermal grids, i.e. district heating or cooling systems, and presents a market-clearing mechanism based on the alternating direction method of multipliers (ADMM) for coordinating between thermal grid, electric grid and DER operation. The ability of the proposed mechanism to achieve the market equilibrium for a combined thermal and electric grid is demonstrated for a test case with 22 flexible loads (FLs).

The problem of intermittent generation peaking is highly concerned by the grid operator. To build control model for solving unbalance of peaking is great necessary. In this paper, we propose reserve classification control model which contain constant reserve control model with real-time reserve control model to guide the peaking balance of the grid with intermittent generation. The proposed model associate time-period constant reserve control model with real-time reserve control model to calculate, and use the peaking margin as intermediate variable. Therefore, the model solutions which are the capacity of reserve classification are obtained. The grid operators use the solution to achieve the peaking balance control. The proposed model was examined by real grid operation case, and the results of the case demonstrate the validity of the proposed model.

After the establishment of the unified and interconnected electricity market in China, electricity trading range will cover the entire State Grid operating region, and headquarters market and provincial market will become interconnected, unified and coordinated operation. Aiming at the surveillance risk under the unified and interconnected electricity market, a relatively complete surveillance risk index system is proposed. The proposed risk index system includes six first grade indices, i.e., market state, transaction plan, contract and settlement, market coordination, energy efficiency and power grid operation. The risk index system can reasonably and overall reflect the risk level of the electric power transaction under the unified and interconnected electricity market circumstances. It is useful for State Grid to achieve risk management and control of electricity trading surveillance, rectify the irregularities, and maintain a fair and impartial market order.
