The EU’s lack of regulatory definition for energy storage is among major factors holding back the potential of the technology in the continent, particularly for integrating renewables, SolarPower Europe has argued in a new report.
(PV-Tech讯)SolarPower Europe日前在一份新报告中表示，欧盟对于“储能”缺乏标准定义是阻碍该技术在欧洲大陆潜力的主要因素之一，特别是对于整合可再生能源。
The trade group, formerly the European Photovoltaic Industry Association, has authored the “Solar and Storage Policy Paper – April 2016” along with the Association of European Automotive and Industrial Battery Manufacturers (EUROBAT) and the European Heat Pump Association (EHPA).
该行业集团，前身为欧洲光伏产业协会，日前与欧洲汽车和工业电池制造商协会(EUROBAT)及欧洲热泵协会(EHPA)一起撰写《太阳能和储能政策文件——2016年四月》。
The trio’s joint proposals outlined in the paper push for the greater recognition of storage as a way to increase the value of solar by enabling greater on-site consumption of PV power, as well as valuing the potential network-side benefits of storage. The latter includes easing pressure on grids by using solar-plus-storage to meet peak demand, which in Europe occurs in the evenings.
通过授权光伏发电更大的现场消耗，以及重视储能在网络方面的潜在好处，在文件中概述的三方联合提议进一步承认储能是作为提高太阳能价值的一种方式。通过使用太阳能加储能来满足欧洲晚间出现的高峰需求，缓解了电网的压力。
In order to get the best use of “zero marginal cost” solar electricity and to get to higher ratios of self-consumption, while potentially also unlocking the use of storage systems to provide demand side flexibility, the report’s authors make a number of recommendations.
为了最佳利用“零边际成本”太阳能电力以及实现更高比例的自发自用，同时潜在开放储能系统的使用为需求方提供灵活性，该报告作者提出一些建议。
Modern networks require modern configuration
现代网络需要现代化配置
First and foremost of these recommendations is to “provide a common EU legal definition of storage”. As has been seen in Europe and markets elsewhere, electricity markets and grids have been historically designed to accommodate centralised, usually fossil fuel-based generation, transmission and distribution of energy.
这些建议中首要的是“提供一个欧盟通用的储能法律定义”。正如在欧洲及其他地区市场看到的，电力市场和电网从历史上来说旨在适应集中，通常是化石燃料发电、输电和配电。
In the case of storage, one of the biggest issues raised by this is that networks are not configured to cope with a device that, like a battery, can be any number of things simultaneously including generator, load or transmission asset, depending on where it is placed on the grid and what it is used for. In many regions such as the UK, this means transmission network operators cannot invest in storage if it would mean becoming involved in the power market too, to give one simple example. At the same time, SolarPower Europe, EUROBAT and EHPA argue that the creation of a European storage market is hampered by this lack of definition.
至于储能，提出的一个最大的问题是没有配置网络来处理电池等装置，同时可能是任何数量的东西，根据在电网的位置以及用途，其中包括发电机、负载或传输资产。举一个简单的例子，在许多地区，如英国，如果储能也没有打算参与电力市场，这意味着输电网络运营商无法投资储能。与此同时，SolarPower Europe、EUROBAT和EHPA认为，欧洲储能市场的创立被缺乏定义阻碍。
An “appropriate framework for self-consumption” is needed, the policy paper also says, urging the EU to create one through its Renewable Energy Directive framework, which currently calls for 20% of the EU’s energy demand to be met with renewables by 2020. Some countries, such as Spain, have levied taxes on PV system owners using their own power, while even Europe’s longstanding PV market leader, Germany, has rules limiting the amount of self-generated power one can use that one industry advocate recently said are “very strange”.
该政策文件还表示，需要“适当的自发自用的框架”，敦促欧盟通过其可再生能源指令框架创建一个，目前指令呼吁到2020年利用可再生能源满足欧盟能源需求的20%。一些国家，如西班牙，对使用自己电力的光伏系统所有者征税，而甚至是欧洲长期以来的光伏市场领导者，德国，日前都规定限制一个人可以使用的自发自用的电力的量，一个行业倡导者最近表示，这“非常奇怪”。
Among the other recommendations for action are a call for greater coupling between energy sectors – electricity, heating and cooling and transport. Storing power in the form of heat, or optimising EV charging to cause the least stress on the grid could also be important in adding flexibility to energy networks. The paper also calls for more R&D and temporary support programmes, such as the limited cash rebate paid to German buyers of home battery storage systems to be rolled out.
行动的其他建议是呼吁能源部门之间更大的结合——电力、加热和制冷以及运输。以热的形式储存电力，或优化电动汽车充电减少电网压力，对于为能源网络增加灵活性也是重要的。该文件还呼吁更多研发和临时支持计划，如推出向家庭电池储能系统的德国买家支付有限制的现金折扣。
SolarPower Europe, EUROBAT and EHPA argue that storage can help make the energy system more cost-effective by allowing the use of power when it is cheaper and by balancing out peaks in pricing throughout the day.
SolarPower Europe、EUROBAT和EHPA认为，通过允许当电力便宜之时对其进行使用，以及通过全天中和峰值价格，储能可有助于使能源系统更具成本效益。
