| 摘要: |
| 随着设施农业的发展，设置合适的控制策略以及利用新型农业负荷可以有效消纳农网的分布式发电功率。区块链因具有安全、共识、激励的特性逐渐受到能源领域的关注。利用设施农业负荷的可时移特性，在农业园区微能网层和温室层分别构建优化目标，提出了基于区块链技术的园区微能网控制策略。各温室以促进光伏就地消纳最大化为目标，基于区块链中共享的用能数据、设备参数、运行数据等信息，针对园区微能网中光伏出力波动、负荷时移、储能配置等提出了下一时段的运行策略。设定光伏消纳占比评价指标，评估各温室的消纳情况，在区块链中始终记录最优的负荷运行方案。算例结果表明，所提控制策略可有效提高园区分布式光伏的就地消纳程度，降低微能网的购电费用和网损，提高电网的电压质量。 |

| Abstract: |
| With the development of facility agriculture, the distributed generation power of agricultural network can be absorbed effectively by setting appropriate control strategies and using new agricultural load. Blockchain has gradually attracted the attention of energy field due to its characteristics of security, consensus and motivation. Based on the time-shift characteristic of facility agriculture load, optimization objectives are respectively constructed in the micro-energy network layer and the greenhouse layer in the agricultural park, and the control strategy of micro-energy network in the park is proposed based on the blockchain technology. With the goal of maximizing local consumption of photovoltaic in each greenhouse, based on the energy consumption data, equipment parameters, operation data, and so on, which are shared in the blockchain, the operation strategy for the next period is proposed responding to output power fluctuation of photovoltaic, time-shift load and configuration of energy storage in the micro-energy network. The evaluation index of photovoltaic consumption ratio is set to evaluate the consumption condition of each greenhouse, and the optimal load operation scheme is always recorded in the blockchain. The example results show that the proposed control strategy can effectively improve the local consumption of distributed photovoltaic in the park, reduce the power purchase cost and network loss of micro-energy network, and improve the voltage quality of the power grid. |
