In order to meet electricity demand, the role of Diesel Power Generation (PLTD) in parts of Indonesia is still very large. Currently, 34.30% of electricity demand in outside of Java-Bali system was supplied by the PLTD. Especially for the Eastern Indonesia (Nusa Tenggara, Maluku, and Papua), nearly 100% of its electricity comes from PLTD. For the next 10 years, the government planning through PT. PLN will install 252 MW of PLTD in Eastern Indonesia and 73 MW in Western Indonesia. Due to the increasing of oil prices in the world will directly increase the oil prices in Indonesia, so that the electricity generating cost from PLTD would alsoincrease. To reduce fuel consumption without reducing the service to the consumer, the construction of Diesel Power Generation should be integrated with renewable energy, like Solar Power and Wind Power to form the Hybrid Power Generation. By the Hybrid Power Generation, energy management can be controlled, so the using of diesel fuel can be more efficient. By applying of Solar Power and Wind Power in a quarter of the capacity of PLTD, the consumption of fuel could be reduced by 152million liters up to 2019, or an average of 15.2 million liters per year.

This paper presents a realization process of a hybrid system consisting of biomass and wind as well as solar power generation on the target region. The installation principle and procedure are introduced based on the conditions of natural energy such as wind speed and solar radiation degree. The output characteristics from 20kW biomass generator is explained and analyzed in according to coop rational possibility with the wind power and solar power system. The operation characteristics of 40kW wind power turbine is provided based on the practical operation data collected within three years and the simulated results obtained from the software calculation. The operation conditions of 20.6kW solar power system is also analyzed based on the solar irradiance density in the located site. The general efficiency of this triple hybrid power system in economic and environment aspects is also studied by using and comparing the simulation methodology and the data in practical operation.

Energy Cluster

Forecasting of large-scale renewable energy clusters composed of wind power generation, photovoltaic and concentrating solar power (CSP) generation encounters complex uncertainties due to spatial scale dispersion and time scale random fluctuation. In response to this, a short-term forecasting method is proposed to improve the hybrid forecasting accuracy of multiple generation types in the same region. It is formed through training the long short-term memory (LSTM) network using spatial panel data. Historical power data and meteorological data for CSP plant, wind farm and photovoltaic (PV) plant are included in the dataset. Based on the data set, the correlation between these three types of power generation is proved by Pearson coefficient, and the feasibility of improving the forecasting ability through the hybrid renewable energy clusters is analyzed. Moreover, cases study indicates that the uncertainty of renewable energy cluster power tends to weaken due to partial controllability of CSP generation. Compared with the traditional prediction method, the hybrid prediction method has better prediction accuracy in the real case of renewable energy cluster in Northwest China.

This chapter deals with three linked issues. First, the nature of modern campaigning, with particular reference to the work of Greenpeace and the solutions they offer. Second, the role of Greenpeace and other nongovernmental organizations from the not-for-profit sector. Third, the challenge and opportunities created by ‘globalization’ and what this means for global governance from an environmental point of view. For some years Greenpeace has argued that ‘solutions’ have moved to centre stage in the work of pressure groups, as they used to be known. The formative role of environmental campaigning organizations was to draw attention to problems, but by the 1990s, finding and demonstrating solutions, and getting them applied, became much more important (see Yearley, this volume). This has proved a long and hard road. Indeed, the gap between what can be done and what is being done has, if anything, widened. This is mainly because the technical potential has improved while, in Britain at least, implementation has moved much more slowly. It was once famously said of an incompetent British government that this is an island built on coal and surrounded by fish, but still it manages to run out of both. Similar things could be said today. The government has patently failed to protect fish stocks but that can be conveniently blamed on the EU Common Fisheries Policy. But no such excuse will wash on energy. Britain’s wave energy resource is more than 70 times the UK electricity demand. Britain’s wind resource is also vast. Offshore wind could meet Britain’s entire electricity demand three times over. Against this, the government’s unattained target of 10 per cent for renewable electricity is simply pathetic. Contrast Britain with Denmark, which is phasing out fossil fuel use in electricity generation and is on course for generating 50 per cent of its electricity from wind alone by 2030. Little wonder Denmark is reaping the benefits in terms of engineering jobs in wind turbines, an industry in which it is world leader. The story in Germany and the Netherlands is similar: yet Britain is far, far windier.

The Impact

Strategic issues facing oil majors in the 1990s are very diffuse — in contrast with both the 1970s (when strategy meant the response to high oil prices) and the 1980s (when it meant anticipating and exploiting a drop in prices). Mainly upstream issues include the future of price management by OPEC or a successor, the speed of development of new markets for natural gas in power generation and the role of Russia in world energy markets. Other issues include the impact of environmental regulations and taxes on the product mix and on marketing. Human-resource management will continue to face the task of reconciling career opportunities with static or declining manpower requirements; and corporate cash mountains may periodically recur.

With the increasingly serious environment pollution and energy shortage problem of further deepening, how to use more effective and more environmental protection equipment of the new energy conversion and utilization of become social the public and the government attaches great importance to the problem. According to the high speed highway car wake contains huge wind, the wind power generation unit born. The vertical shaft by double S rotor, wind deflector, variable speed clutch institutions, centripetal vertical pendulum and low speed generator composition , realized respectively the wind energy collection, transmission, temporary and transformation. This device for wind power generation field provides a more efficient energy conversion mode. Among them, we creatively applied the ratchet, vertical pendulum mechanism so that the wind energy conversion rate has been increased greatly. At the same time, can also solve the highway electric equipment of the power supply problem. This device design makes the highway lighting lamps and other electric equipment of the power supply problem to obtain the very good solve, reduce power facilities installation cost. The effective use of natural wind, expand the scope of the use of wind energy, alleviate energy nervous, also reduce the pollution of the environment.

This paper presents the development of hardware testbed for implementing grid connected wind-solar power system. A solar simulator using halogen lamp is employed to simulate the sun irradiation. The wind power simulator is developed by coupling the DC motor and the DC generator. A grid tie inverter is employed to connect the power from the solar and wind power system with the grid system. The experimental results show that the developed testbed could be used for testing the hybrid power system in the real hardware.
