摘要
新型能源体系下各类型角色的主体即源网荷储的数量会大量增加,主体之间需要协同运行来实现电量平衡、电力平衡。电量平衡是一段时间内的总发电量等于总用电量与损失电量之和,与负荷随时间的变化无关;电力平衡是发电出力等于用电负荷与线损负荷之和,与负荷随时间的变化紧密相关,即当负荷发生变化时,发电出力可以及时地实现新的平衡状态。新能源发电可控性低,几乎不可能及时跟上负荷变化,大规模高比例新能源渗透后,导致电力平衡与电量平衡难以实现,需要通过“源网荷储互补”进行解决。“源网荷储互补”需要打破源、网、荷、储各自的体制,不论供给侧的光伏发电、小风电、燃气冷热电三联供机组、电采暖、电制气、生物质制热锅炉、电源热泵、空气源热泵、余热余压回收等,还是消费侧的用电、用气、蓄冷蓄热储电储气、用冷热(供暖、蒸汽、热水等)、电动汽车充电等,需要突破能源各自的原有体制壁垒,打破原有的各自独立的规划运营方式与调度方式,统筹规划统一运行;促进横向多源互补、纵向“源网荷储”协调,形成集中供能和分布供能相融合的多能互补系统。针对城市、城镇、工业园区、机场、火车站、商业综合体等,通过政策、体制、机制、技术的多重驱动,催生电力产业新业态、消费新模式,释放新动能,提升新质生产力。
Under the new energy system,the number of entities with various types of roles,that is,source,grids,load and storage,will increase significantly,and the entities need to operate collaboratively to achieve power balance and balance.Power balance is the total power generation within a period of time equal to the sum of total power consumption and power loss,regardless of changes in load over time.Electricitybalance means that the power generation output is equal to the sum of the power load and the line loss load,and is closely related to the change of load over time.That is,when the load changes,the power generation output can achieve a new balance state in a timely manner.The controllability of new energy power generation is low,and it is almost impossible to keep up with load changes in time.After large-scale and high-proportion new energy penetration,it is difficult to achieve power balance and power balance,which needs to be solved through"source-grid-load-storage complementation"."source-grid-load-storage complementation"requires breakthroughs of separate systems,regardless of supplyside systems including photovoltaic power generation,small wind power,CCHP,electric heating,electric gas production,and biomass heating boilers,power source heat pump,air source heat pump,waste heat and pressure recovery,etc.,or consumption side systems includingelectricity,gas,cold and heat storage,electricity and gas storage,cold and heat(heating,steam,hot water,etc.),electric vehicle charging,etc.It is necessary to break through the original institutional barriers of each energy source,break the original independent planning,operation and dispatching methods,and coordinate planning and unified operation.Promote horizontal multi-source complementarity and vertical"source-grid-load-storage"coordination to form a multi-energy complementary system that integrates centralized energy supply and distributed energy supply.Targeting cities,towns,industrial parks,airports,train stations,commercial complexes,etc.,by multiple drives of policies,systems,mechanisms,and technologies,the new business formats and new consumption models in the power industry will be spawned,new momentum will be released,and new quality productive forces will be enhanced.
