具体实施方式
本发明实施例提供了一种电能调度方法和装置、电源管理方法和装置,用于采用基站中的储能电池作为电网的储能容器,成本较低且电能转移效率较高。
为了使本技术领域的人员更好地理解本发明方案,下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅仅是本发明一部分的实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都应当属于本发明保护的范围。
本发明的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”“第四”等(如果存在)是用于区别类似的对象,而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换,以便这里描述的实施例能够以除了在这里图示或描述的内容以外的顺序实施。此外,术语“包括”和“具有”以及他们的任何变形,意图在于覆盖不排他的包含,例如,包含了一系列步骤或单元的过程、方法、***、产品或设备不必限于清楚地列出的那些步骤或单元,而是可包括没有清楚地列出的或对于这些过程、方法、***、产品或设备固有的其它步骤或单元。
请参阅图1,本发明的一个实施例中电能调度方法包括:
101、电能调度装置确定第一时段和第二时段;
在通信***中,每个基站中都配备有储能电池,用于在基站断电时向基站供电,以保证基站的正常运行,并在基站得到正常供电时从该基站所连接的电网存储电能,以在基站下一次断电时向基站提供电能。
在电力***中,电网将发电电站所转换生成的电能输送和分配给各个用电负载。发电电站每单位时间内所处转换成的电能是一定的,而各用电负载的用电量在不同的时间段是不一样的。在部分时间段,各用电负载的用电量较大,甚至会超过电网所能提供的电量,当总用电量超过一定数额(称为上限值)时的时间段称为电网的负荷高峰时段;在部分时间段,各用电负载的用电量较小,电网中有大量电量剩余,当总用电量低于一定数额(称为下限值)时的时间段称为电网的负荷低谷时段。需注意的是,在不同的地区,电网的负荷高峰时段 以及负荷低谷时段不一定相同,而且定义电网达到负荷高峰时段和负荷低谷时段时所用到的上限值和下限值也不一定相同。
本实施例中,电能调度装置对至少一个基站的储备电池进行管理,用于控制该各个基站中的储备电池从电网存储电能以及向电网补偿电能。其中第一时段为电能调度装置控制各基站的储能电池从与该基站连接的电网存储电能的时段,第二时段为电能调度装置控制各基站的储能电池向与该基站连接的电网补偿电能的时段。
在负荷低谷时段,由于电网中有大量电量剩余,为更充分的利用资源,本实施例中,第一时段优选与该负荷低谷时段至少部分重合。在负荷高峰时段,电网承载较大压力,为避免给电网带来更大压力,本实施例中,第二时段优选与该负荷高峰时段至少部分重合。当然,上述描述仅为举例,并不作限制。电能调度装置也可以根据实际具体情况来决定第一时段和第二时段为其他时段。
102、所述电能调度装置向至少一个基站发送第一指示信息,所述第一指示信息用于控制所述基站的储能电池在所述第一时段从所述基站所连接的电网存储电能;
电能调度装置向基站发送第一指示信息,用于控制基站的储能电池在第一时段从基站所连接的电网存储电能。接收到第一指示信息的基站的储能电池开始存储电能。
103、所述电能调度装置向所述至少一个基站发送第二指示信息,所述第二指示信息用于控制所述基站的储能电池在所述第二时段向所述基站所连接的电网补偿电能。
电能调度装置向基站发送第二指示信息,用于控制基站的储能电池在第二时段向基站所连接的电网补偿电能。接收到第二指示信息的基站的储能电池开始向电网补偿电能。
本发明实施例中,通过电能调度装置统一确定第一时段和第二时段,并在第一时段以其所连接的至少一个基站的储能电池作为储能容器,将电网的电能转移存储至该储能容器中,并在第二时段采用该储能容器向电网补偿电能,由于现有的每个基站中都配备有储能电池,采用各基站的储能电池作为电网的储能装置,无需额外的成本投入,并提升基站的储能电池的利用价值;而且,电 能在电网和各基站的储能电池之间的转移效率较高,避免了电能在转移的过程中损耗较大而造成电能的浪费。
上面实施例中,电能调度装置需确定第一时段和第二时段。实际运用中,电能调度装置可通过多种方法来确定第一时段和第二时段,下面对本发明实施例中电能调度方法进行描述。请参阅图2,本发明的另一个实施例中电能调度方法包括:
201、所述电能调度装置从所述电网获取所述电网的负荷预测数据;
电能调度装置可以通过与电网的电网调度***或者电网服务器获取该电网的负荷预测数据。当然,实际运用中电能调度装置也可以从其他处获取该电网的负荷预测数据,在此不作限制。负荷预测数据是根据以往的电网负荷变化做出的对未来一段时间内的负荷预测,反映了未来一段时间内电网负荷随时间而变化的规律。具体地,电能调度装置所获取的负荷预测数据可以包括日负荷预测数据、月负荷预测数据、季度负荷预测数据或者年预测数据。
由于电网的负荷预测数据会不断更新,因此,电能调度装置优选每隔预置时间或者在预置时间点重新获取电网的负荷预测数据,以对所获取的负荷预测数据进行更新。当然,由于电网负荷随时间变化的规律波动一般不大,实际运用中,电能调度装置也可以不对负荷预测数据进行更新,在此不作限制。
202、所述电能调度装置根据所述电网的负荷预测数据确定所述电网的负荷低谷时段和负荷高峰时段;
由于电网的负荷预测数据反映了未来一段时间内电网负荷随时间而变化的规律,电能调度装置可以根据该规律确定电网的负荷低谷时段和负荷高峰时段。实际运用中,电网自身已经定义有当电网的负荷低于多少值时为负荷低谷时段,高于多少值时为负荷高峰时段。电能调度装置可以直接根据电网自身的定义来确定电网的负荷低谷时段和负荷高峰时段。或者,电能调度装置也可以自定义当电网的负荷低于多少值时为负荷低谷时段,高于多少值时为负荷高峰时段,并根据该自定义来确定电网的负荷低谷时段和负荷高峰时段。
203、所述电能调度装置将所述电网的负荷低谷时段确定为第一时段,将所述电网的负荷高峰时段确定为第二时段;
电能调度装置确定好电网的负荷低谷时段和负荷高峰时段后,将该负荷低 谷时段确定为第一时段来控制基站的储能电池从电网存储电能,并将该负荷高峰时段确定为第二时段来控制基站的储能电池向电网补偿电能。
204、所述电能调度装置向所述基站发送第一指示信息,所述第一指示信息用于控制所述基站的储能电池在所述第一时段从所述基站所连接的电网存储电能;
详细说明请参见图1所示实施例中步骤102的说明。
205、所述电能调度装置向所述基站发送第二指示信息,所述第二指示信息用于控制所述基站的储能电池在所述第二时段向所述基站所连接的电网补偿电能。
详细说明请参见图1所示实施例中步骤103的说明。
本发明实施例中,电能调度装置通过从电网获取电网的负荷预测数据并根据该数据确定各基站的储能电池从电网存储电能的时段为电网的负荷低谷时段,以及确定各基站的储能电池向电网补偿电能的时段为电网的负荷高峰时段,这样,电能调度装置以其所连接的至少一个基站的储能电池作为储能容器,在电网的负荷低谷时段将电网中的电能转移存储到该储能容器中,以在电网的负荷高峰时段能够使用该储能容器所存储的电能,能够减轻电网在负荷高峰时段的压力以及在电网的负荷低谷时段时的充分利用电能资源。
本实施例中,电能调度装置通过步骤201至步骤203来获取第一时段和第二时段。实际运用中,由于在电网的负荷预测数据中,电网的负荷随时间的变化规律非常明显,且在很长一段时间内保持稳定。因此,电能调度装置也可以不是通过步骤201至步骤203来获取第一时段和第二时段,而是通过接受并存储第一时段和第二时段的预先设置。
具体举例来说,在工作日中,早上9:00-12:00以及下午的14:00-18:00一般为电网的负荷高峰时段,晚上22:00-6:00一般为电网的负荷低谷时段。因此,可在电能调度装置中预先设置第一时段为工作日的晚上22:00-6:00,第二时段为工作日的早上9:00-12:00和/或下午的14:00-18:00。当然,以上对第一时段和第二时段的描述仅为举例说明,并不作限制。
甚至,实际运用中,也可以不是根据电网的负荷低谷时段和负荷高峰时段来对第一时段和第二时段进行预先设置,而是根据其他实际需要来对第一时段 和第二时段进行预先设置,在此不作限制。
电能调度装置接收并存储对第一时段和第二时段的预先设置,并在需要时从存储位置调用该第一时段和第二时段。
实际运用中,电能调度装置在控制各基站的储能电池从电网存储电能或者向电网补偿电能时,各基站的储能电池的状态有可能不利于从电网存储电能或者向电网补偿电能,因此,优选的,本发明实施例中还对各基站的储能电池的状态进行检测,下面对本发明实施例中电能调度方法进行描述。请参阅图3,本发明的另一个实施例中电能调度方法包括:
301、电能调度装置确定第一时段和第二时段
详细说明请参见图1所示实施例中步骤101的说明。
302、所述电能调度装置检测至少一个基站各自的储能电池分别在所述第一时段前和所述第二时段前的状态;
实际运用中,由于电池并不是在任何时候都能任意进行存储电能和向电网补偿电能,例如电池电量为零时则不能向电网补偿电能,电池电量为满额时则不能存储电能。或者,实际运用中,在不同的运用情况下电池的存储电能和向电网补偿电能需满足一定的条件。
因此,本实施例中,在电能调度装置确定第一时段或第二时段后,在控制所管理的各个基站在第一时段存储电能或在第二时段向电网补偿电能之前,还要对所管理的各个基站的储能电池分别在第一时段前和第二时段前的状态进行检测,再根据该储能电池的状态来决定是否要从电网存储电能或向电网补偿电能。由于储能电池的状态在一定时间内会比较稳定,因此电能调度装置具体可以在第一时段或第二时段前的预置时间内对该储能电池进行检测,其中该预置时间的具体数值不作限制。
303、当所述基站的储能电池在所述第一时段前的状态满足第一预置条件时,所述电能调度装置向所述基站发送第一指示信息,所述第一指示信息用于控制所述基站的储能电池在所述第一时段从所述基站所连接的电网存储电能;
第一预置条件可以有多种设定方式。例如,当基站的储能电池的电池健康系数大于第三预置数值时,该储能电池的状态满足第一预置条件。或者,当基站的储能电池的荷电量小于第一预置数值时,该储能电池的状态满足第一预置 条件。当然,上述对第一预置条件的描述仅为举例说明,并不作限制。
确定基站的储能电池在第一时段前的状态满足第一预置条件后,电能调度装置向基站发送第一指示信息,用于控制基站的储能电池在第一时段从基站所连接的电网存储电能。接收到第一指示信息的基站的储能电池开始存储电能。
304、当所述基站的储能电池在所述第二时段前的状态满足第二预置条件时,所述电能调度装置向所述基站发送第二指示信息,所述第二指示信息用于控制所述基站的储能电池在所述第二时段向所述基站所连接的电网补偿电能;
第二预置条件可以有多种设定方式。例如,当基站的储能电池的电池健康系数大于第四预置数值时,该储能电池的状态满足第二预置条件。或者,当基站的储能电池的荷电量大于第二预置数值时,该储能电池的状态满足第二预置条件。当然,上述对第二预置条件的描述仅为举例说明,并不作限制。
确定基站的储能电池在第二时段前的状态满足第二预置条件后,电能调度装置向基站发送第二指示信息,用于控制基站的储能电池在第二时段向基站所连接的电网补偿电能。接收到第二指示信息的基站的储能电池开始向电网补偿电能。
本发明实施例中,通过电能调度装置先对各基站的储能电池的状态进行检测,当各基站的储能电池在第一时段前和第二时段前的状态分别满足预置条件时才控制各储能电池存储电能和释放电能,保证了各基站的储能电池的安全工作。
在以上各实施例中,电能调度装置向所述基站发送第二指示信息,用于控制所述基站的储能电池在所述第二时段向所述基站向电网补偿电能。实际运用中,为保证各基站的储能电池在断电时能够为基站提供保障,各基站的储能电池在第二时段向电网补偿电能时并不是直到储能电池的电量放完才停止,而是留有一定余量,下面以一具体实施例来对本发明中的电能调度方法进行描述。请参阅图4,本发明的另一个实施例中电能调度方法包括:
401、电能调度装置确定第一时段和第二时段;
详细说明请参见图1所示实施例中步骤101的说明。
402、所述电能调度装置向所述基站发送第一指示信息,所述第一指示信息用于控制所述基站的储能电池在所述第一时段从所述基站所连接的电网存 储电能;
详细说明请参见图1所示实施例中步骤102的说明。
403、所述电能调度装置向所述基站发送第二指示信息,所述第二指示信息用于控制所述基站的储能电池在所述第二时段向所述基站所连接的电网补偿电能;
详细说明请参见图1所示实施例中步骤103的说明。
404、当所述基站的储能电池的状态满足第三预置条件时,所述电能调度装置向所述基站发送第三指示信息,所述第三指示信息用于控制所述基站的储能电池停止向电网补偿电能。
至少在第二时段中,电能调度装置保持对基站的储能电池进行监控。当检测到基站的储能电池的状态满足第三预置条件时,指示该基站的储能电池停止向电网补偿电能。该第三预置条件可以由多种设置方式。例如,为使得基站的储能电池中剩余有预置电量来保证基站在断电时的正常运行,当基站的储能电池的荷电量小于预置电量时,确定基站的储能电池的状态满足第三预置条件。
实际运用中,也可以通过其他方法来确定第三预置条件。具体举例来说,本实施例中,电能调度装置还获取所述基站的储能电池的荷电量和健康系数、所述基站的业务空闲系数,以及所述基站所连接的电网的稳定性系数。
该电能调度装置可以在进入第二时段时或者进入第二时段前预置时间内获取这些数据。基站的储能电池的健康系数可根据该储能电池的电池健康度SOH来获取。具体举例来说,当该储能电池的电池健康度SOH大于或者等于70%时,该储能电池的健康系数取值为1;当该储能电池的电池健康度SOH小于70%时,该储能电池的健康系数取值为0。当然,该储能电池的电池健康度SOH和健康系数取值之间也可以采用其他对应关系,在此不作限制。或者,该储能电池的健康系数也可以通过该储能电池的其他系数来确定,在此不作限制。或者,实际运用中,该储能电池的健康系数也可以根据该储能电池的电压、电流、内阻、电池温度等其他参数来确定,在此不作限制。
基站的业务空闲系数可以根据该基站的负载功率比来获取,其中该基站的负载功率比为该基站的当前负载功率与该基站的负载功率上限值的比值。具体举例来说,基站处于高业务量时,定义为该基站的负载功率比大于或者等于 80%时,该基站的业务空闲系数取值为0;基站处于正常业务时,定义为该基站的负载功率比小于80%且大于50%时,该基站的业务空闲系数取值为0.5;基站处于低业务量时,定义为该基站的负载功率比小于或者等于50%时,该基站的业务空闲系数取值为1。当然,基站的负载功率比和业务空闲系数之间也可以采用其他对应关系,在此不作限制。
基站所连接的电网的稳定性系数可通过该电网在该基站工作时段的停电时长来获取。具体举例来说,当电网在基站工作时段的停电时长与基站的该工作时段的比值大于或者等于50%时,该电网的稳定性系数取值为0;当该比值小于50%且大于25%时,该电网的稳定性系数取值为0.5;当该比值小于或者等于25%时,该电网的稳定性系数取值为1。当然,电网在基站工作时段的停电时长与基站的该工作时段的比值,和基站所连接的电网的稳定性系数之间也可以采用其他对应关系,在此不作限制。或者,基站所连接的电网的稳定性系数也可以根据电网的电压、电流、功率等其他参数来计算,在此不作限制。
获取到每个基站的储能电池的荷电量和健康系数、该基站的业务空闲系数,以及该基站所连接的电网的稳定性系数后,电能调度装置根据该储能电池的荷电量和该三个系数来计算该基站的储能电池的放电深度阈值。
具体举例来说,可将每个基站的储能电池的荷电量和健康系数、该基站的业务空闲系数,以及该基站所连接的电网的稳定性系数这四个数值的乘积作为该基站的放电深度阈值。当然,实际运用中,也可以通过对该四个数值进行其他运算,例如先计算每个基站的储能电池的健康系数、该基站的业务空闲系数和该基站所连接的电网的稳定性系数这三个系数的加权值之积,再将该基站的储能电池的荷电量与该加权值之积的乘积作为该基站的放电深度阈值。上述对计算的描述仅为举例说明,并不作限制。
为便于理解,下面以一个实际应用场景对本实施例的电能调度方法进行描述。
电能调度装置从电网获取该电网的周负荷预测数据,其中在该电网的日负荷预测数据中,根据电网对负荷高峰时段和负荷低谷时段的定义以及该日负荷预测数据,电能调度装置确定每天晚上22:00-6:00为电网的负荷低谷时段,并将该负荷低谷时段确定为第一时段;电能调度装置确定每天早上10:00-12:00 以及下午的15:00-18:00为电网的负荷高峰时段,并将该负荷高峰时段确定为第二时段。
电能调度装置同时与位于同一地区中的20个基站进行通信,并检测这20个基站各自的储能电池分别在第一时段前5分钟内(也即每天的21:55至22:00)和第二时段前5分钟内(也即每天的9:55至10:00和14:55至15:00)的状态。当检测到这20个基站中各基站的储能电池的状态满足在第一时段前5分钟内的荷电量小于第一预置电量时,电能调度装置向满足该条件的基站发送第一指示信息,该第一指示信息用于控制该基站的储能电池在第一时段从该基站所连接的电网存储电能。当检测到这20个基站中各基站的储能电池的状态满足在第二时段前5分钟内的荷电量大于第二预置电量时,电能调度装置向满足该条件的基站发送第二指示信息,该第二指示信息用于控制该基站的储能电池在第二时段向该基站所连接的电网补偿电能。
