计及需求侧响应的微能源网日前调度及定量评估

DAY-AHEAD SCHEDULE AND QUANTITATION EVALUATION OF MICRO-ENERGY NETWORK CONSIDERED REQUIREMENT-SIDE RESPONSE

为最大限度消纳可再生能源,提高能源利用率,减少资源浪费,提出一种包含风、光可再生能源、微型燃气机组、电转气(P2G)以及各种储能设备的微能源网模型;并在此基础上将用户侧的电、热柔性负荷纳入需求侧响应资源,以微能源网综合运行成本最低为目标函数构建微能源网孤岛状态下日前调度模型,然后利用Cplex求解器求解模型;最后从能源侧以及负荷侧引入评价指标函数,对不同场景下调度结果进行定量评估,证明计及需求响应下包含P2G与微型燃气机组的微能源网系统能实现能源的高效利用、节约运行成本,提升孤岛状态下的供电可靠性。

Being an indispensable carrier of energy Internet,micro-energy network plays an important role in realizing the coordination and optimization of various energy sources as well as the cascade operation of energy.In purpose of maximizing the consumption of renewable energy,improving the utilization rate of energy and reducing the waste of resources,this paper proposes a micro-energy network model including renewable energy that is from wind and light,micro gas units.Power to gas P2G and various energy-storage equipment.Power of users’platform and thermoflexible loads will be accepted into the requirement-side response resources at the basis of this,this paper constructs day-ahead schedule model under island of energy network in the purpose-function of Minimum cost for comprehensive operation of micro energy grid,and solve the model with the CPLEX solver.Finally,this paper brings into evaluation index functions from the energy side and the load side,carrying out quantitative evaluation of schedule results in different scenarios,and turns out that the micro-energy network system including P2G and micro-gas units under requirement-response can achieve efficient utilization of energy,save operation cost and improve the reliability of power supply under the island.
