What is the CCHP microgrid energy management strategy?

The CCHP microgrid energy management strategy includes three stages: a day-ahead economic scheduling stage, an intraday rolling optimization stage, and a real-time adjustment stage.

How a microgrid can achieve efficient and graded utilization of energy?

Microgrid, which contains renewable energy, various energy transmission devices and energy storage devices, can achieve efficient and graded utilization of energy by planning and scheduling the output of each unit to meet the demand of user-side load , , .

What is the optimal scheduling strategy for microgrids?

In order to balance the accuracy, economy and robustness of microgrid scheduling better, a multi-time scale optimal scheduling strategy for microgrids considering the uncertainty of source and load is proposed.

Does the MPC control method reduce the cost of a microgrid?

The intra-day scheduling cost and the total cost of the microgrid under the MPC control method are reduced compared to the DAS strategy, which indicates that the MPC control method is able to reduce the cost by scheduling energy transmission devices to smooth out the forecasting errors. Table 5.

How does a microgrid work?

The microgrid mainly uses gas storage tanks to store gas during the 2–5 h when WT, PV output is high and electricity prices are low. At the same time, P2G is used to convert electricity to natural gas during the 1–8 h and 19–24 h, which not only provides space for wind power consumption, but also further reduces the system's energy purchase cost.

How to improve CCHP microgrid economic dispatch plan?

The dispatcher adjusts of the CCHP microgrid. predict accurately. Therefore, it is necessary to add a better real-time intraday predictive control optimization scheduling link to correct the economic dispatch plan. The intraday predictive control plan. The CCHP microgrid energy management system’s cold and hot load and wind power generation
