Grid Integration

The Netherlands’ renewable energy sector has reached an agreement with the country’s grid operators and power providers for a faster grid connection of solar parks. PV plant operators will be able to connect their projects at 70% of their capacity and, in turn, they will be allowed to connect them without having to wait for more grid availability.

PV developer Sun’R Power and wind-power specialist Boralex have revealed plans to connect part of the Cambrai-Niergnies solar project and the Seuil du Cambrésis wind farm to a single private substation.

As some parts of Australia’s distribution networks threaten to black out under the flow of rooftop solar exports, ARENA announces funding for a trial that will enable flexible exports in line with what the networks can bear. Smart software is the answer.

The International Renewable Energy Agency wants consultants to prepare a plan for grid expansion across West African countries. The ECOWAS region currently has only 16 GW of power generation capacity, with 32% of it from hydroelectric facilities and 68% thermal power.

Australian scientists have identified seven methods to prevent PV losses when overvoltage-induced inverter disconnections occur. The methods include battery storage, reactive power inverters, export limits, distribution static synchronous compensators, the replacement of old conductors in power grids, load reconfiguration, and dynamic voltage restoration.

When Covid-19 hit his small solar engineering business, chief executive Methode Maniraguha said: ‘No furloughs or layoffs – we’ll pivot.’

LF Energy has launched its Digital Substation Automation Systems initiative, in hopes of creating a more modular, flexible and resilient grid. It aims to make interoperable substations that are both hardware and software agnostic.

Bill Gates and Breakthrough Energy see enhanced transmission as facilitating electrification and grid reliability. Increasing transmission development at the “seams” between regions could save consumers more than $47 billion and return more than $2.50 on every dollar invested.

The Australian Energy Market Operator (AEMO) claims that the country already has the technical ability to safely operate a system in which three-quarters of the electricity comes from wind and solar. However, it needs to get the regulations right in order to do so.

Researchers from Finland’s Lappeenranta University of Technology have assessed the economic advantages of a fully interconnected global network. They found that an international grid could contribute to a global LCOE of €52.50/MWh. The higher complexity of such a system, however, would only be marginally compensated by additional economic benefits.
